Foot

Something you can get up your ass if you're not careful

yo you want my foot up your ass? then shut the hell up

Pee

Something I need to do desperately but I'm too entertained with urban dictionary bullshit

like really... I'm 2 seconds away from pissing myself. I should go or the pee is not going to make it to the toilet, it will be like 5th grade all over again when I pissed myself and some kid came out of nowhere and slipped on my pee. THAT SHIT WAS HILARIOUS THOUGH and in my defence that kid was a little bitch. okay why the fuck am I still typing??
