Pump Troll 

A short, young female who enjoys sex in every way possible.

That little pump troll took it in all three holes and begged for more.

A sex act in which a man attaches a strap-on to his backside, facing rearward. Two women then situate themselves in front of and behind the man, one receiving his penis, the other being thrust into by the strap-on during his back stroke. This technique maximizes the man's time and energy while pleasing two ladies simultaneously.

Your mom and sister only had a few minutes while your dad was out, so a pump trolley was our only option.

Saint Petersburg Pump Trolley 

When you shit in one hand and then fist someone in the ass with it, while reaching around and pouring vodka in their mouth with your other hand

I just shit in my hand and am feeling kinda turned on by it, I might offer someone a Saint Petersburg Pump Trolley.
