Verb- The Shelly-Lexi is a simple sexual activity. There are two participants. The first inserts his or her left fist into his or her own anus. The other participant carefully inserts both of his or her fists. The participant with both fists in the anal cavity is known to propose marriage in this position and put the ring on the finger. This is how you know when it's true love.
Dude 1: "How are you going to propose? Beach, fancy dinner, what man?"

Dude 2: "I don't know man, I was thinking The Shelly-Lexi"

Dude 1: "Wow you must really love her"
