Black Twitter is mocking rapper A$AP Rocky after his girlfriend, Rihanna, dressed up as another mumble rapper for Halloween.

Those of you who celebrate the pagan holiday know that a lot of thought and effort goes into designing your costume.

Just the idea that Rihanna put that much thought into dressing up as another man - and not her man - should concern A$AP.

I would have a talk with my girlfriend if she dressed up as another blogger instead of me.

A$AP began dating Rihanna last year after she dumped (or got dumped) by Saudi billionaire Hassan Jameel.

The Internet is having a field day dissecting Rihanna's costume. They say she wants Gunna to know she has a crush on him.

The fact that she went to such great lengths to dress up in a Gunna costume probably means Rihanna tried to holla at him -- but got rejected.

They say Gunna is already taken.

If you recall, the barrel-chested rapper was hospitalized with pneumonia recently. His rumored lover Young Thug made a big show out of visiting his bedside and presenting him with not one, not two, not three, but four very expensive watches.

A$AP, who was born Rakim Mayers, previously dated Calvin Klein model Jasmine Daniels. He has also been plagued with teh ghey rumors for most of his career.
