Turnt is a variation of "turned" used only to describe when someone is excessively excited or prepared for the current event. In it's entirety, it can commonly be seen used as "
turnt up," as in "turned up."
A real
Debbie Downer, party pooper, or
lame-o, would be someone who is turnt down. They simply are neutral in their stature, and unfit for the current event. Alcohol and or/ drugs would be suitable aid to turning them up.
"David just downed 7
Jager bombs and is fucking that girl from downstairs while wearing your
rollerblades, dude! He got so
turnt!"
Not to be used in such a manner as this:
"Captain! I have turnt the wheel right of the indigenous islands. These are not the lands you're looking for."
