Jahlil Okafor -- You're Gonna Get Hazed, Bro ... Says 76ers Teammate

Hope Jahlil Okafor enjoys public humiliation ... because according to one of his new 76ers teammates, the #3 pick in the draft has some serious hazing coming his way.

We spoke with Philadelphia's Hollis Thompson -- who tells us the team's got some fun stuff in store for the big man ... just like he had to go through when he was a rookie.

FYI -- the NBA hazing isn't too crazy ... Portland made their rookies wear pink Hello Kitty backpacks. Washington made their rooks tie the veteran's shoes. Golden State made their guys do the Gangnam Style dance.

But Thompson says he remembers his own NBA hazing like it was yesterday -- thanks to one former teammate who made him do a ton of "dumb stuff."
