glass bottom boat 

A sexual act in which the customer lays under a glass coffeetable and looks up through it, while their partner defecates on the top. How some people find this stimulating I'll never know.

Also can refer to the same positioning with a coffee table but the person on top merely presses their genitals onto the glass, for "squashed" visual effect - or can refer to defecating onto someone's face which has been first covered in plastic kitchen wrap like Saran Wrap.

Your grandfather got arrested in Thailand again after paying an underage transvestite hooker for some ]glass bottom boat] action.

Working on the boat 

Working on the boat is a euphemism for masturbating. Our friend would give an excuse for not hanging out with us by saying that, "he was working on the boat". Eventually we got so bothered by his "working on the boat" that we went to his house and asked his mother and she told us that he was in the bathroom. However he didn't exit the bathroom for 45 minutes. Thus he was "working on the boat".

Person 1: Hey were going over to my house, want to come?
Person 2: Sorry, I gotta work on the boat.

Person 1: Where were you man?
Person 2: Sorry, I was at my house working on the boat.

tow boat 

When someone is blowing you in a pool and you are walking backwards "towing" them around the shallow end with your knob while making motorboat noises. A variation would be the steamboat, this would be done in a hot tub instead.

I am banned from the public swimming pool for life after doing the tow boat in front of all of those families with that lifeguard last month.
