One who fences with an epee.
 

The standard stereotype of an epeeist (mostly true):

Epeeists are tall. Very tall. A group of very tall men and women lounging on a street corner are either basketball players or epeeists. The difference is that basketball players will help a little old lady across the street, while epeeists are more likely to take her purse and throw her over. There is no real epee "costume", except that they tend to wear track suits and shave their heads. Their women are the most beautiful of all the fencing women, but also the most likely to knife random passers-by and take their wallets.

All epeeists wear very expensive running shoes which they have invariably stolen.  It is a mark of shame in the epee subculture to wear legally-purchased footwear. Naturally this is difficult to ascertain merely by looking, and of course asking about it can lead to other complications.
