a slap happy hellacopter
You're trying to get some head, but your cock is as soft as a baby's f***ing cheek. So you grab it, twist it like a f***ing windmill, and whack her with it like you're trying to wake her up.
My cock was softer than my ex's promises. So I twisted it and slapped her awake.
He had to twist his cock like a f***ing pizza dough to slap her.
I slapped my date with my cock like it was a f***ing f***ing slap bracelet.
