well i mean the only boom that I cd hear in bangalore was from the posteriors of heavy dark damsels in jeans or slacks which made them look as if shakila(the kerala version) was poured in clothes made for carol gracias(the skinny model), I mean I am yet to hear a boom different from that which results due to a combustible mixture of vada pav with coke in the bellies of these damsels and the gaseous results of which they then dispense with such abandon in almost all the shopping malls and through the entire length of brigade road.
