The act of dropping a shot of Jagermeister into a glass filled with the energy drink Red Bull and imbibing sai concoction. Not to be confused with beerosaurus rexes or vodkaraptors.
Dude, at Frankie J's last night, I must have slayed about 7 or 8 Jagerdactyls. I found boots of +4 drunknisity. It's a rare drop.
