Silver Pin Down 

To engage in a friendly, playful round of Greco-Roman Wrestling with your Grandfather during which you are pinned to the floor, inadvertently fondled and able to feel his erect penis poking you. Typically result in an immediately yelling of "I give" and no further discussion or wrestling ensues.

Dan: Hey Carl. Want to take a ride with me? I need to run this assisted living brochure over to my Grandpa's house.
Carl: No thanks Braaaaahhhh. I still am scarred from the last time I went with you there. Not this time. No way I am getting the Silver Pin Down again brooooohhh!!
Dan: Oh come one brother!! I can't wrestle him by myself. It's too awkward when Grandma's gone.

T-Rilla Pindown

A sexual game involving a blindfolded man, anally receptive partners, and a dildo. The game involves a man who is blindfolded while other men are lined up on all fours encircling him. The blindfolded man then feels his way around and shoves the dildo into the first hole he can find. The one who receives is considered the “winner” and in exchange gets to have his way with any of the men he chooses, and is then blindfolded for the next round. Vaguely similar to the childhood game “pin the tail on the donkey”.

Guy #1:"Dude, look at that guy. He's walking like he's got a shit in his ass
Guy#2: "Damn, looks like he just got back from a T-Rilla Pindown"
