#%@! can be used to censor words that wouldn't be appropriate to write uncensored, for whatever reason.

The most annoying piece of shit in the world. It is commonly used by attention seeking whores. Some uses for it USED to be:
Number sign
Sharp sign (in music)
Tic tac toe grid

But now thanks to twitter its a "HASHTAG". Used by annoying people.

Some people who use it:

99% of my school
Whores
Obnoxious hypocrites
Anybody I hate

Bob: #YOLO
Joe: #SWAG
Tom Ato-Brain: #WCW #MCM
Idiot: #SELFIE (which is becoming a word in the DICTIONARY)
Me: #ihateallofyou

The short way for saying hashtag, which is the better way of saying pound sign, which is the short word for the ridiculously long word octothorpe.

OMG! There's a frickin' # about me! It's #AWESOME
