Tangs is a slang word referring to a specific object of desire/importance/neccesity. The word is not neccesarily used to indicate a wanting of more than one object, that is, it is not neccesarily considered 'plural' in certain context. The phrase "gimmie' dem'" is most typically uttered before this word resulting in the sentence "Gimmie' dem' Tangs". This is not a command of sorts, that is, it is meant to be fulfilled, but the phrase it only spoken among a group of guys chillin waiting for ladies.
-Tangs is typically used to describe an object that is the facilitator of a soon-to-be pleasureable/beneficial event in which all parties involved with the owner of the tangs partake.
