look up any word, like bae:
 
1.
1. Blanus is a blend of the phrase, "bleaching my dirty anus". Blanus is really for the neurotic on the go. They're a mover and shaker, a jetsetter, and can't be bothered with a blemished anus. Persistent sufferers of swamp ass will sometimes resort to a blanus to keep some of the fecal matter our of their sweaty run off. When wiping your ass just doesn't do the trick, and you find yourself looking in a mirror through your legs at your spread cheeks and your exposed asshole, giving yourself the stink eye back, you're well on your way to a blanus.
What're you doing tonight?" "I'm going home for a blanus" "Do you mean you're gonna scrub bleach on your anus?" "I don't have time for you.
