Did you think you'd heard the last of the man-words? (Quick refresher: man-novation, manscaping, man laws, manorexia, mankini.) No way, bro. Urban Dictionary, ever with its big meaty paw on the pulse, offers this:
A blend of man and panther, it's the masculine form of cougar (an older woman who preys on younger men, as in last week's very funny episode of 30 Rock).
According to the top-ranked Urban Dictionary definition, a manther is:
An older man who frequents bars, lounges and clubs, never a genuine gentleman, ranging from ten to fifty years older than his victim. Usually carries an unusually fat wallet, wears too much cologne, and dresses younger than his age. May over-frequent the tanning beds and gym, have trendy/dyed facial hair such as a soul patch or goatee, may use the terms "baby", "sugar tits", or other female defamation when trying to pursue his prey. If balding, may never take off his ball cap in order to hide his aging hairline. Manthers always seem to evade the question of their age, previous or current marriages, children, and most things regarding their past (unless it has to do with thier old frat/college football days).
To sum up, with apologies to Ogden Nash:
If called by a manther / Don't anther.
