Hit the road Joe ... and don't you come back no more, no more, no more, no more -- cause your son just stopped paying the rent.
Lamar Odom has had it with his dad and will no longer pay his rent ... and the clock is ticking before Joe is thrown out on the street.
Joe Odom tells TMZ ... Lamar called him earlier this week and went BALLISTIC over the comments Joe made about him and the Kardashians.
Joe claims Lamar has been paying his rent for 4 years -- a hefty tag of $2,900 per month -- but Lamar made it clear to Joe ... he's on his own now.
Joe tells us he can't afford the rent ... so he'll be out at the end of next month -- barring a reconciliation.
