it makes sense
Sarcastic phrase that means "I'm right...admit it" even when what you said makes no sense at all. Best used by David Spade in the film "Tommy Boy"
Example:
Bob: "I'm gonna bet my life savings on Chuck Norris going gay...it makes sense doesn't it?"
Bob: "I'm gonna bet my life savings on Chuck Norris going gay...it makes sense doesn't it?"
