Mexican-Spanish slang for an extremely hard/huge penis.
When you are really horny and you're dick is fucking rock hard (from being soooo horny) and it feels larger than usual (like having the highest hard penis ever), then, you have a wesso. If you are watching porno and a guy comes out with a giant cock (like long-dong silver), then, you say he has a wesso.
