Random Dick Ride. Not to be confused with "Red dead redemption". This is used when unknown people start to agree with the person you're arguing despite not knowing the context of the argument when it started.
John: Alex never talk again bro. You're actually dogshit at this game. I literally just killed you with a fuckin pistol LOL.

Alex: You literally ran after me while I was at 10% HP, AFTER RESPAWNING after I KILLED YOU lol. You already died to me multiple times when you were full health.

Unknown Random: Imagine unironically dying to a pistol in this game, and then start to mald in chat like a bitch. You're ass at the game. Could never be me.

Alex: You just joined the server though? RDR moment.

Stands for Raw-Dogging Randoms: The act of going out with your homeboys and finding some drunk and dirty girls (randoms) and taking them home with you and doing them right. One strict rule of RDRing is that you MUST NEVER see or hear from the randoms again.
Yo bro, check out those drunk ass chicks over there!
Are you ready to RDR tonight?
Hell Yeah! I love me some randoms!

The practice of Ramming Dudes Rawdog
"When Chris got thrown in the drunk tank he totally got RDRed in the shower."

"Hey Ceaser, did you wear protection with that dude you met at the Purple Dolphin last night?" "No you silly goose egg, I RDRed him."

(AKA Rump Raidering)
