Ruben is such a guy harvey.

Whatever, guy harvey. You're so dumb.
Its when you are laying in bed and getting head from the girl. (you dont give her the tap out before you blow your load in her mouth) Then just before you are about to blow your load, you take your finger and fish hook her in the ass. This makes the girl start to squirm around like a fish on a hook and then you unleash your load into her mouth.
