Get the lamer mug.
Before the rise of the Internet, it was largely used amongst the Amiga pirate, as well as, the demo-scene community.
A lamer would be a wanna-be hacker with absolutely no coding/cracking skills at all.

Also, it was used as an insult between rival pirate groups.
Quartex are lamers!

A "Lamer" a person acting lame, one who plays an online game deathmatch style or RPG's to enjoy him/herself disregarding others want to have fun playing that game too.

Basicly a Lamer is a coward, a camper, a troll, a cheater, anything that spoils the online gaming experience of others.
In a mmorgp a lamer would only combat much lower leveled players,
In an online shooter a lamer would hide and "frag" bypasser neglecting he has other goals to do, in team based games a Lamer will stick to the winning team even if its clear that changing would make the game more fun for everyone.
