J 

The Ultimate-Guitar.com (UG) version of the pound sign (£) - it is common amongst hard-core patriotic users to use this replacement (J) outside of context and UG...

J or j can be used - both are acceptable.

This replacement of 'J' and '£' arises from the personal messaging system. It inexplicably replaces '£' with 'J' before sending, presumably because it cannot store or send '£' as it is not a letter, and as UG is American, the £ is unlikely to be used.

- Oh that's about J180 isnt it?
- cheapest I've seen is J500!

;j 

A new type of emoticon, used in many different situations, mostly in gaming:
1: when you do something good, unexpected, or skillful
2: when trolling someone
3: when people try to make jokes that are "comedy gold", (used the emoticon in excess)
4: when being a jerk
examples:

A) when playing Starcraft 2, and you micro completely perfectly
"Dude that was total BS, how did you do that, hacker" response: " ;j "

B) (playing any sort of game such as Super Smash Bros, where 1 person is extremely more skilled than the other)
skilledperson: *infinite juggles the other person*
otherperson: CMON man give me a chance
skilledperson: ;j

C)

person1: Hey man you should CUM over to my house XD
person 2: ;j;j;j;j;j;j;j;j ;j ;j ;j ;j
