literal definition is dick sniffer but in Puerto Rico in means like a bad friend, bad boyfriend, asshole, idiot, you-should-die, etc. It's ghetto Puertorrican slang.
Pronunciation: Well-eh, or well-ee; depending on the continent. Wele is the actual "fruit" part of a fruit. It is the good tasting part, in between the peel and the pit, seeds or other disgusting non-foods.
