Kiss ass, as in "make nice", usually to compensate for some major jerk move you pulled. Loosely translated from Spanish to form a "Spanglish" word (though this variation has been considered slightly controversial because culo sometimes is taken to mean asshole, so you are not just kissing the ass-cheeks, you are going WAY in there!).
Oh, shit dude, I came in at 5am last night, smellin' like perfume, so I had to majorly beso culo so wifey didn't kick me out of the house!
