speed fingering 

The competitive sport of trying to get the quickest time between meeting a girl for the first time and fingering her. Many "bros" compete with their "bros" to get the quickest time. Many times "bros" will be on a mission to speed finger before they meet the girl to get a quicker time.

Me and my bros went out to go speed fingering. I got a girl in 47 minutes and my homie did it in only 15 minutes!
