The title refers to what happens to a skydiver when his parachute doesn't deploy: you hit the dirt at very high speed and most likely die.
Oh man, his parachute didn't open. Prepare for some high speed dirt!

Get the high speed dirt mug.
The act of taking a shit really quickly. Named after the Megadeth song of the same name, which is, coincidently, shit.
"Oh no, she's coming round in three minutes!"
"You better take a high speed dirt"
