Mine are easy:

Gaucho100K (He likes my country and my tipple, how could I not want to meet him?)
Dovster (Lechery and a sense of humor)
Stimpy (he hangs out in France, and other intersting places)
BearX220 (I am a sucker for aircraft knowledge)
JDiver (anybody that addicted to scuba must have other redeeming qualities aslo)

Nobody else seems to justify their choices but my mother always made me do that. There are so many more...
