noun: a penis that is severely infected with any number of venereal diseases (mostly the worst ones out there like syphillis, clamidia, etc.). A penis that has nasty fluids and puss filled bumps on it and is really the worst thing that can happen to anyone. The reason its called "Vegas Cock" is because not everything that happens in Vegas stays in Vegas (i.e. it comes back with you in your pants).

Las Vegas NV. This town of glitz, lights, gambling and entertainment has a reputation as a mecca of sin and sex. Sure, the place is amazing if your single; single female that is. With a male to female ratio of about 12 guys for ever girl, Cock Vegas is an oasis of penis. Many guys have claimed that Alaska has more available chicks then Cock Vegas, and that is saying something. Go to a club; it gets up to 56 guys and 5 girls. Some clubs have even enforced a 1 to 1 ratio and you have men lined up around the block twice trying to get in. Las Vegas and San Diego ( Cock Vegas and Man Diego ) might as well be brothers in pecker. On Industrial road where the strip clubs and "Swinger" clubs are, which to a local are well known rip offs, have an endless flow of cock shooting off dollars and cents.
Go to anyplace, online, and see for yourself. Experience Cock Vegas for yourself.
