pee pressure
The act of compelling one's comrade to urinate in a public area.
Paulina G: Watch this. I am totally going to pee pressure Kendra into pissing in this dark, sketchy alley.
Pee-r Pressure
When one of your friends announces he or she has to pee, and suddenly you have to pee, too.
I thought I could make it the whole flight without going to the bathroom, but when Nicole and Eric went, I really started feeling the pee-r pressure.
Pee group pressure
The desire not to be left out when a group of friends decide to take a pee break at the public toilets.
Yeah, I didn't need to go, but I didn't want to miss out on all that gossip, so I gave in to pee group pressure and pretended I had to go as well.
