gangbusters

Gang Busters was a famous radio program that was first heard in 1936 and aired until 1957. The sound effects of police sirens, tommyguns, and screeching tires that opened the show were dramatic and exciting -- this inspired the expression 'coming on like gangbusters'.
Usage has opened up to describe things that are not just exciting, but successful, intense, and many other adjectives, and many drop the 'coming on like' prefix. I think we should be more careful about how we use it, and keep it true to its origin -- something that starts with much excitement and drama is 'coming on like gangbusters'.

The rainstorm late last night came on like gangbusters!

Gamester 

Short for videogamester, combining (video)gamer and gangster. A person who is part of a certain game community engaged in an online gang war with another such community such as Xbox vs. Playstation, Infinity Ward vs. Treyarch, PC vs. console and so on. Possible symptoms of gang affiliation are overzealous brand loyalty, arguing on youtube, basically having nothing more important to talk about and virginity.

"Jim keeps sending me these links to those horrible Xbox 360 vs. Playstation 3 graphic comparison clips whenever a new game comes out."

"I take it he then starts bitching about how the colors look more realistic on one console than the other? And when the other idiots who comment on youtube disagree, he starts talking about the tv-screen they used for the clip and how biased they were?"

"Exactly, he's a total gamester. I told him to fuck off and then I just had sex with my girlfriend."
