Reving The Crowd 

To Rev the crowd is an action that is preformed at a concert by the lead singer (most likely).

To get the crowd at a show more rowdy, a band member may rev the crowd by placing both hands in the air above his head (like riding a chopper bike) and like you would do on a motorcycle to rev the engine, you twist your hand up and down.

Revving up a lawnmower 

A two part sexual act.
The first part of the act consists of forgetting to use a lubricant on Anal Beads before inserting them into anal cavity of an unsuspecting sexual partner.
The second part is simply a quick removal of unlubricated sex toy in a manner similar to revving up a lawnmower, causing severe damage to the sex partner.

Dude, I once knew this goth girl that was into butt stuff. She wanted me to bead her up, but I forgot to use the lubricant and ended up lrevving up a lawnmower]
