rocket lawnchair
"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?
