Boston alarm clock

Waking someone up by ejaculating on their face.

Did you hear about the guy suing the YMCA? He was taking a nap and some dude gave him a Boston Alarm Clock.

Boston alarm clock

When you pull your pants down, straddle a bum's face, and fart on it to wake him up.

I just gave that hobo that sleeps outside of Tony's Pizzeria the old Boston alarm clock.
