sweanus
Sweanus.....after a workout, or hot summer day, or some steamy intercourse, the moisture that develops in the crack of your ass, is called, sweanus. More often than not, it refers to someone in the negative....because they may have actually just not showered in days, therefore creating a funky odor from 'back there'. Combines the two words sweaty and anus.....sweanus, VOILA!
