Rob49's New Orleans slang has spread to the entire country -- the platinum-selling rapper's "WTHELLY" catchphrase has completely engulfed social media!!!
TMZ Hip Hop linked up with Rob this week out in Burbank, CA and he tells us lingo was something he and his friends kicked out around -- and he decided to popularize the phrase over a banging beat!!!
It's carefree nonsense -- the type of stuff TikTok eats up. There's love and some hate but it's got everyone talking -- except for Rob's b-ball hero LeBron James!
