When you are gettin a chick from behind who has long hair, grab the hair and thoroughly wipe off your dick after you've finished. Keep in mind guest towels are for decoration only so if you use it, dont expect another invite.
Your Roommate: Hey, whatever happened with that chick you brought home the other night?
You: Oh, she wont be back, I used the guest towel.
You: Oh, she wont be back, I used the guest towel.

When it becomes necessary to exit a chick's apartment via the window because you realized too late that you are drying your ass and junk with her "guest towel" after bangining the shit out if her"
I wasnt paying attention and i had to make a guest towel get-a-way. Man I dont know which i left messier, her or her goddam linens.
