When a guy has a girlfriend who is way out of his league.
"Did you see his wife?! Yeah, he definitely out-kicked his coverage."
Dating or marrying a woman that you can't possibly satisfy, thereby assuring she will be back on the market in a short period of time.
Bill: Dude, is that Gary's wife?
Tom: Yeah, she's really hot isn't she?
Bill: Hell yeah, he really out kicked his coverage on that one.
