Despite A$AP Rocky's close, brother-like bond with A$AP Ferg, it turns out there are still some unforgivable betrayals. Ferg recently found that out the hard way.

Although the pair has exercised their unique sense of humor countless times over the years, A$AP Rocky didn't see one particular prank coming and not only did he fall victim to Ferg's trap, but he reacted perfectly when he found out that Ferg had seemingly used his toothbrush (gasp!). 

A$AP Rocky took to Instagram to explain how disgusted he was with Ferg's personal hygiene, detailing in depth how appalled he was that Ferg really had the lack of decency to use his personal toothbrush to clean his clippers.

"That n***a used my toothbrush to clean these bum a** clippers," Rocky says while showing the camera the dirtied bristles of his brush. "F**k is he talking about. That's the disrespectful s**t. Ferg's supposed to be a good boy. He's supposed to be the Hood Pope. This isn't very Pope-ly. Cleanliness is next to Godliness and this isn't very Godly. Why did he disrespect me?"

From there, he doesn't let it go, hilariously wondering aloud what would happen if he didn't notice his toothbrush was dirty and actually used it. 

During the revelation, he realizes he may have been set up, yelling loudly, "Ferg! Stop using my toothbrush!"

Ferg then walks in and the two start laughing. Regardless of whether or not this was just a prank, we trust that Rocky will be keeping his toothbrush far, far away from Ferg in the future.
