look up any word, like cunt:
The state that one becomes when they get high from marijuana. Originated from the phrase " getting retarded", however, much cooler people refer to it as being "tadded".
Sometimes when one gets extremely high it is called "way too tadded", but when someone gets even higher it is called "mega ultra tadded".
"Hey man I'm way too tadded right now"

"Too bad your not ultra mega tadded" said Mach.
