When a slick dude probes a womans rectum with his finger without her consent, then swiftly attacks her mouth with the shitty finger. 'The Dipstick!' is then typically announced afterwards.
Mikes a fuckin perv... he stuck a finger in my ass, and when I pulled it out he stuck his crap-encrusted finger in my mouth and shouted 'dipstick'

A dipstick is when an individual walks up to an unsuspecting (seated) female victim and proceeds to stick his finger down her partially exposed ass-crack. He then looks her in dead in the eye and sniffs his fingers. Always a good ice-breaker.
After chad dipsticked kerry at unh in 2006, she knew they would be together forever.
