MTD 

Multi Track Drifting

Often used in Trolley Problem Memes.
In a Comic (Densha de D) there is one rather famous picture of a train with front and back wheels on different rails and a character saying "Multi Track Drifting".
This merged with the Trolley Problem memes, as you can kill all 6 people tied to the tracks by multi track drifing.

Trolley Problem Meme: "There are five vegetarians tied to a track and a trolley is approaching which will overrun them. You can save them by pulling a lever which changes the trolley's track to one where only one vegan is tied. What do you do?"
Comment: "MTD!"

MTD 

MTD, or MySpace Transmitted Disease, is something you implicitly have when you are added by a girl with a webcam. They are nasty people, who in all likeliness do not care who they ask to be their freinds, they just want to be "watched". These can also be contracted by people who are added by MySpace whores, aka people with over 200 friends who are not musicians.

"'Hey man, check this out! 'hi! i'm jennifer and i'm kinda new to this, but ur 2 cute!!! i also have a ****free webcam**** check it out!!!!' 'Sick, I can already feel the MTD settling in.'"
