Rocket Lawnchair 

Another, more humorous way to say Rocket Launcher.
Popularized by Metal Slug X and it's hilarious announcer.

Upon picking up an R symbol, Marco heard someone shout "ROCKET LAWNCHAIR!" in their ears from absolutely nowhere.

"rocket lawnchair" is basically another way of naming the n00b wep0n of choice in fps games like halo 3,cod4, and shadowrun. actually saying the word instead of saying rocket launched acxtually results in more lulz..

im surprised that this isnt a definition yet...this IS urban dictionary right?
