Self-Deprecating Sarcasm

Self-Deprecating Sarcasm is a humor when you get slightly and randomly roasted on.

Example:

"Hey bro what are you doing for Valentines Day, oh wait nevermind you don't have a valentine."

Self-Deprecating humor is only funny to the person telling the joke, normally not funny for the person getting roasted on.

Example:

Lakers Fan: "Hey did you see the Basketball game last night?"

NBA Fan: "No sorry I don't watch bad teams"
