Spanish to English Other Slang Argentina

This term came up in an Argentine TV series I'm working on the subtitles for. I am very curious about it. I have found other instances of it online, but no actual discussion regarding the term itself.

I am wondering if this is used (or was used) in a similar way to how some Colombians use "gonorrea" as both an insult and, in certain circumstances, somewhat of a term of affection among friends (along with "marica").

I found this on the RAE website for "manga," which is a definite step in the right direction:

21. f. despect. coloq. Arg., Bol., Par. y Ur. Grupo de personas. Una manga de atorrantes.

Perspective from any Argentines would be greatly appreciated! Thanks in advance.
