speed trapping 

The art of perfectly timing a fart, right as a person passes behind you, so you fart on the said person, leaving the aroma on them as if they had farted.

Be careful of that guy over there. He has been speed trapping people all morning.

Speed Tapping 

The physical stimulation of repeatedly tapping the anus (aka sphincter) with one or more fingers in a rhythmic beat. Done for the sensation of pleasure, relief of stress, or out of shear boredom on a hot summer day.

1. Speed tapping helps me unwind after a long day.

2. Patient: “Doc, I’ve got a giant lump on my sphincter. What should I do?”
Doctor: “Son, you’re going to need to lay off the speed tapping for a few weeks.”

3. "I did a little speed tapping on the ol' snare drum (anus) last night."
