When you're camping and you need to pee but there isnt any actual toilets so you must squat in the woods.
Katie: OMG i have to pee soooo bad but i dont know if i should go in the lake or the bushes
Jess and Kellie (singing to the tune of row row row your boat): Katie has to pee, but cant make up her mind! she had better pop a squat, or we'll leave her behind!
