Kendall & Kylie Jenner -- Trap Queens for Ex-Duke Superstars

Former Duke stars and NBA first rounders Jahlil Okafor and Tyus Jones are teaming up again -- this time to holla at Kendall and Kylie Jenner ... Fetty Wap style.

Tyus and Jahlil -- like many NBA players, we suspect -- were hot on the sisters' tails Thursday ... using Twitter to reach out.

Our pals at BSO pointed out the ballers' tweets -- using "Trap Queen" lyrics.

Not horribly creative on the ex-Dukies' parts, but we'll give 'em partial credit for effort, and for waiting until after Kylie's 18th birthday. So far, doesn't look like either Jenner sis has followed Tyus and Jahlil.
