Nibin

Nibin: meaning 'humble' in Latin. Nibin is probably the sexiest guy around but he wont tell you that. He is the kinda of guy you want by your side when fighting off an army of 10,000 pygmies with poison arrows. He can tell you what color your underwear is by looking into your eyes. He is wanted in three countries by the authorities. He is wanted in 162 countries by most women. He can eat a cheeseburger in 1 bite. He can lick his own elbow and other peoples too. Scientists have said that he is so hot that he may be the main reason for global warming. His shit doesn't stink, in fact it smells like car polish. He was refused entry to the USA because his biceps were classed weapons of mass destruction. He is in the Guinness book of world records for completing the most somersaults in a row (126,253). We spends: Mondays at orphanages, Tuesdays at homeless shelters, Wednesdays at retirement homes, Thursdays developing a cure for AIDS, Fridays playing racquet ball with Bono and Sting and Weekends writing prize winning novels.
It is also slang for having a huge dick.

"Wow never knew he had that he must have been a Nibin"
When I walked in on Nibin in the bathroom I never knew a white boy could be so huge!
