2.
Comical Jamaican slang for a severely obese female. The "boom-boom" is denoted NOT for the sound she makes when she walks, but for the onomatopoeic reference to the way in which the fatty tissue “bounces” during movement; especially in regards to the breasts and biotical areas, but also applies to the arms, legs, and abdomen. Generally, too big to be appealing.

5.
Commonly used name for the Chelsea and England midfielder Frank Lampard, a.k.a Fat Frank, Frank Lump-a-lard and Lardy the ground trembler. He is described as Fatty Boom Boom not only for his increasing girth but also due to his weight of shot - he has a right foot like a cannon though without the precision rifling that would confer accuracy. Most of his shots fly over the bar.
"Would someone tell Fatty Boom Boom to pass the ball to Gerrard rather than blasting it over the bar."
"That Fatty Boom Boom couldn't hit a cow's arse with a banjo"
