50 Cent and Waka Flocka Flame both have long histories of very provocative statements.
Fif tends toward trolling, while Waka tends to say outrageous things that often don't make sense.
The two may be headed for a showdown after Waka dropped a big subliminal that seemed to be aimed right at 50's personal life.
Yesterday, 50 Cent gave an interview in which he offered his most detailed explanation of why he disowned his 23-year-old son Marquis, who he says is an entitled brat.
Today, Waka fired off this message.
"Can't f*ck wit a person that don't f*ck with their own kids," Waka typed.
Last year, Waka checked Fif for his negative comments about Michael Jackson.
Do you think there's any chance Waka isn't talking about 50 now?
