This is when you're desperately needing
some head, but
your girl's asleep. Therefore, you sneak into the room and stick your dick in her mouth while she's sleeping. By
instinct, she'll probaby start sucking your dick while sleeping, giving this action the name "Sleepy Head"
Friend 1- Man, the other night my girl was asleep and I really needed
some head.
Friend 2- I guess that left you to use your right hand for the night,
Friend 1- Nah man. I just
stuck it in her mouth and she gave me some
sleepy head.
