Maybe this is why Gregory and Marcia Abbott allegedly bought their daughter’s way into college.

Their “rapper” son, Malcolm, popped out of the family’s Fifth Avenue building to smoke a giant blunt — while defending his parents and bragging about his latest CD.

“They’re blowing this whole thing out of proportion,” said Malcolm Abbott outside the home that overlooks the Metropolitan Museum of Art. “I believe everyone has a right to go to college, man.”

In between drags, Malcolm, whose father is the founder of food and beverage distributor International Dispensing Corp., admitted, “I didn’t go to college.”

The toker, who sports a ponytail and raps under the name “Billa,” then shamelessly plugged his music. “Check out my CD, ‘Cheese and Crackers,’ ” he said of his 2018 five-track rec­ord that includes a song titled “If I Lost My Money.”

Later, Malcolm emerged with his brother, who groused to The Post on Tuesday his parents “got roped into [this by] some guy who f–king cheated them.”

The parents are accused of paying admitted mastermind William “Rick” Singer $125,000 to boost their struggling daughter’s ACT and SAT scores.

Singer paid off an alleged crooked test proctor to inflate the girl’s scores to a perfect 800 on the SAT math exam and 710 on the literature test. On the ACTs, her score of 23 out of 36 was upped to a near-perfect 35, according to court filings.

Both parents were out on $500,000 bail each.
