Girlfriend's Friend: Why's your boyfriend running around the garden with a boner?

Girlfriend: We didn't have sex last night, so he's a MERP

Girlfirend's Friend: Ahhh I see

Girlfriend: After he's run around for a bit, i'll give him some lube and he'll be fixed after a few minutes in the bathroom.
