Rude

The current slang definition amongst Teenagers and twenty-somethings is cool, awesome, hot, or lit. Much like the last example given,lit, or the first example,cool, the actual definition of the word is completely different from the current slang definition.

1: That nineties grunge band tee is so rude.
2: The pan sexual from tinder that I went out with last night picked up the check and came back to my place. She was RUDE.
