medical: "I have to urinate."

polite/formal: "I have to go to the bathroom (U.S.)/loo (U.K.)"

slang: "I have to pee."

slang: "I have to take a leak."

informal: "I have to take a piss." OR "I've got to take a piss." (This is a bit vulgar, but it's very common in informal situations...among friends etc.)

Thanks so much for your response.what about

I have to take a pee.
Is it incorrect?

Shahid, Doctors would prefer you to say ''urinate''. ''Pee'' is slang for ''urinate''. Shahid, what do you mean by ''incorrect''?

Just say " I need to go to the toilet" or " I need to be excused"

''restroom'' and ''bathroom'' are better words to say than toilet in public places.

I'm need to go the toilet. (most popular)


I'm going to the loo (used in the south of England)

Toilet = A public toilet
Bathroom = a private toilet (because it normally has a bathtub in it)

I'm gonna go to the "BOG" seems to be a vulgar popular term used in the UK, by young men.

In the U.S,

Restroom = A public room with toilets
Bathroom = A private room with toilets and it normally has a bathtub.
Outhouse = A bathroom that is not connected to the rest of someone's house.

''I have to take a pee.'' Isn't this a redundancy for ''I have to pee''? ''I have to take a piss'', What about just ''I have to piss''? Is ''I have to piss'' any common?
Fon   Wednesday, March 24, 2004, 20:23 GMT
Standard: I have to urinate.

Standard: U.S I have to use the bathroom/restroom. U.K. I have to use the loo.

Slang: I have to pee

Slang: I have to take a whiz/leak

Vulgar: I have to take a piss.

Redundant: I have to take a pee. Or is it?

It sounds weird, but that's the nature of idioms.

I would suggest a simple "excuse me". Beyond that it's nobody's business.
