The release of several small farts warning that a turd is on it's way.

Warning Shots 

First twitches of the male orgasm. Purposely subdued in an attempt to prevent a full orgasm and prolong the experience. May or may not produce ejaculate.

"When you're getting close you pull out. Sometimes you can stop the warning shots and you can go at it again and then finish up."
