Si

An unbelievably rich cunt (richer than Bill Gates) who wears a monacle and probably has other characteristics but none you really care about.

Also likes boys and sniffing the sweatline under fat guys flabbing man breasts.

Brian has loads of money for beer tonight. He could do a Si and buy the pub free drininks all night.
