One's ability to endlessly rage with reduced hangovers and increased physical and mental performance. Requires audacity and a willingness to party with beautiful women during all times of the day and night regardless of previous obligations and current physical conditions. (Warning: attempting to increase one's fratima may result in death. It can also result in getting laid. Consult your local fraternity before attempting to increase one's fratima.)

I need to go home and sleep. It's getting late, I'm sick, I have homework, and I had a little too much. (chick)
I don't because I have fratima!!!! Let's rage!!!!! (hotter/better looking chick)
You need to work on your fratima. I've blacked out 9 days in a row and I'm still good!!! (hardened party animal)
