Dude, Mark has got a rat tail!
Often confused with the Colombian necktie, this is where the tongue of an individual is cut and placed sticking out of their rectum.
Person 1:They found out tony was snitching, and gave him a Laotian rat tail.
Person 2:Is that where they slit your throat and pull your tongue through.
Person 1: Nah it’s where they cut your tongue off and place it sticking out yo ass. Kinda like it sticking its tongue out at you.
Person 2: Uh, my bad.
