Rob Kardashian's threatening texts to Pilot Jones may not contain overt threats -- but they do seem to contain homophobic and racist references in them, reports TMZ.

Last week, we reported that the reality star was being investigated by LAPD's Threat Management Unit after sending some unsavory messages to the dude who sold pics of himself making out with Blac Chyna, and insinuated he might be the true father of her unborn baby girl. 

Rob unleashed on the wannabe singer via text after the photos went viral -- and it's pretty ugly.

TMZ is reporting that Rob sent the following texts to Pilot, which he subsequently took to the LAPD:

     -- "And u fa***t ass bitch this is ROB and u did the most DISRESPECTFUL s**t ever by releasing pics and a story to a pregnant Woman who is 17 days from having a baby!"
    -- "This is my Wife and you about to get your ass beat by every Mexican in LA including me."
    -- "U f***ed with the wrong Woman and the wrong dude."
    -- "I hope you religious cuz after I beat your ass with about 30 Mexicans u better hope God lets u into heaven."
    -- "Its a wrap for u and after we beat your ass we will all be good and never contact Chyna ... u pu**y ass n***a."
    -- "Don't ever come for me and my wife ever U corny ass n***a"

Huh?! What do those texts even mean?! Does Rob think he's Mexican?!

The LAPD is investigating but the outlet says that the police think that the offensive texts are a little "murky and general."

Chyna has stated on Instagram that Pilot is actually gay, and that he used the photos to get back at his ex. She claims his motivation in doing all of this was to get publicity for his new single.
