You: Its nighttime, shouldn't we be heading to bed?
Boy Roommate: Ok, are you Top or Bottom?
You: Uhhhhhhh
Boy Roommate: No dumby, bunk beds.
You: Thank God.
Boy Roommate: But if you wanna, we can...
You: *faints*
Listen up, buttercup. This joke is about a dude who's worried about sharing a room with another dude. He thinks the roommate is making a move on him when he asks "top or bottom". But the roommate is just talking about bunk beds! Then the roommate tries to actually make a move and the dude passes out. You probably would too, you are weak.
