Based upon the introductory social practice of gripping another's phallus in an overhand fashion, and providing an unrequested and unsanitary, yet meaty, sweaty, and oddly satisfying handjob, engaged in by boy scout masters to their pledges once their parents' minivans get lost on the horizon. May also be accompanied by a frigid and unsolicited finger in the anus or a halitosis-laden and toothy rimjob. Because hey, Traps are gay, but a mouth is a mouthand 20 bucks is twenty bucks.
Look man I have a buyer lined up for the drugs! You gonna tell me where they are? Or you wanna give me the ol' Scoutmaster's Handshake all day!?!

Get the Scoutmaster's Handshake mug.
Greeting another male by grabbing their genitals instead of their hand.
My neighbor gave me a scoutmasters handshake at the block party last summer...and every day since.
