Retrofart 

When you have to fart but hold it in for so long, you hear it gurgle back into your tummy.

Gillian: Dude, what's that noise?
Lillian: Yo man, I just retrofarted to save you from my wicked SBD.

Retrobass 

Retrobass (aka RB) is an independent british-asian electronic musician, technologist and multimedia artist originally from London (UK). He is known for single-handedly developing his own form of 'positive-alternative' hiphop & electronica; a unique blend of electro, industrial, rock, dub & downtempo fused with positive vibes, catchy melodies, lush ambient textures, phat synths, raw urban beats & elements influenced by his east-indian heritage. RB made his debut online in late-2005 with his 'socially-conscious' tracks "No Fear!" & "HeroIN Veins Feat. Russ.J". This was later followed-up by the innovative alternative-hiphop/dnb track, "Shanti Om", which received worldwide attention after being pre-released on Myspace for World Peace Day (21 September, 2006).
