Why Prep?

English Slang 
 & a few Idioms 

Note:  This is NOT a comprehensive list.



This is a work in progress.  There is too much slang and too many idioms in the English language to teach all of them here.  But, I'll try to teach as many as I possibly can, which to be honest, isn't very often.

This work has been a last priority with me, because I do not consider the knowledge of slang and idioms essential to international communication.  However, they are fun to learn, and may actually be of help to the acquisition of English by giving learners implicit insight to the workings of the English language. 


Any questions about English slang?

Abbreviations Used Below
[U] = Uncountable
[C] = Countable

Definitions of Terms

Slang [U]:  the whole collection of words (not phrases), which constitute colloquialisms which are generally NOT in the dictionary (or lexicon), but are common in speech.

Idiom [C]:  a single phrase, which generally (but not always) has two meanings: (1) the literal meaning, and (2) the figurative meaning.

Literal meaning:  the meaning of the individual words retain their original semantic value.  (i.e., sum of parts = whole)

Figurative meaning:  the meaning of the individual words is naught, and the collection of all the words in the phrase take on a completely different meaning.  (i.e., sum of parts does NOT equal the whole)

A few Idiomatic Expressions
in alphabetical order


boo boo

Definition:  injury

Sample sentence:  Did you get a boo boo?

Linguistic Notes:  Used mostly with children (young children)

buck (dollar)

Original Definition:  originally "bucca" = a male goat;  or, "buc" = a male deer

Slang Definition:  a dollar bill (North American slang).

Origin of "buck" as a meaning for a dollar bill:  It comes from "buckskin", which was a common unit of trade in the "Old West" of North America.  It is therefore a metaphor.  While a buckskin may not have been the same value as a dollar bill, the common ground was that both were basic units of trade.  [source:  Online Etymology Dictionary]

For more info about metaphors, see my figures of speech page.

"Jane Doe" and "John Doe"

Definition:  Jane Doe is a woman and John Doe is a man; both with no name.  It is usually used for a corpse with no identification.



Definition:  A "jerk" is a bad person, i.e. a person who has treated another individual badly.

Origin:  There must be a connection between the real meaning of jerk and the slang meaning of jerk.  I think if someone jerks another person (physically) it would hurt (a little), and if someone jerks another person (emotionally) it would hurt (a lot).  That's why we call such a person a "jerk."  [I'm guessing this is a kind of metonymy.]  AND/Or it comes from the idiom:  to jerk sb around, which means:  to treat somebody badly.



Original Definition:  jockey (a person who rides a horse in a horse race)

Slang Definition:  any athlete



Definition:  toilet bowl; toilet; WC; restroom; lavatory

Origin:  The man who invented the commode (the flush toilet bowl) was named John Craps.  Possible this slang word comes from the man's given name.  But, it is only a possibility.  I'm not sure about the origin of this slang word.


killer (adj)

Definition:  something that is "to die for" (see slang entry ...die for);  something that is extremely coveted

Sample sentence:  Dude!  Those are killer shoes.


long johns

Definition:  long, thermal underwear.

Sample sentence:  It's cold out.  Be sure to put your long johns on.



Original Meaning:  average, common; low-class, base

Slang Meaning:  unkind

Linguistic Note:  this isn't slang anymore, because I see that this meaning has been added to Merriam-Webster's Unabridged online dictionary as definition number 7.  But, I'll leave it here, because if you are not using an up-to-date dictionary, it won't be in there.  It has been in extremely wide use as long as I have been alive, and I was wondering when they'd get around to putting it in the lexicons.  Well, I guess they've finally done it.


pee pee & poo poo

Definitions:  pee pee = toddler slang for urine; poo poo = toddler slang for


to photo bomb
