The average femanazi is a hypocritical dictator and a sexist. They tend to believe the male gender is conspiring against women and show no restraint in heaving up utter nonsense, which they refer to as 'an argument'.
Femanazi: EVERYBODY, YOUR BRAS ARE CAGES MADE BY MEN! THEY DON'T LIKE SAGGY BREASTS SO THEY'RE IMPRISONING YOU! WOMENS RIGHTS!
Male 1: What's she talking about, dude?
Male 2: She's a Femanazi, just pretend she isn't there. Hopefully she'll go away.
A gesture originating from the Northern Irish county of Fermanagh but used in both halves of the country. It is used whilst driving on Ireland's roads, especially country roads where one often needs to give priority to other drivers. The index finger (usually of the right hand) is lifted an inch or two from the steering wheel as an acknowledgement.
Well I've let him pass, and he's given me the Fermanagh Finger so he has.
