Pete Davidsonhas a new theory to explain why his ex-fiancéeAriana Grandeonce made a TMI remark about what he’s packing below the belt.

On Saturday, the 25-year-old comedian performed with friends at the Tarrytown Music Hall in New York, and he wasn’t afraid to poke fun at the aftermath of his relationship with Grande, also 25, from whom he split in October.

Opening up about the singer’sinfamous commentabout the size of his penis — and continuing theirtradition of oversharing— Davidson joked about why he thought it was a “mean” but “also genius” move.

“I don’t like that she talked all that s— for my penis,” theSaturday Night Livestar remarked during his stand-up performance.

“Everything is huge to her,” he continued. “Why would she tell everyone that I have a huge penis? So that every girl who sees my d— for the rest of my life is disappointed.”

In addition to her since-deleted tweet about Davidson’s size, Grande seemingly made a reference to it in herMean Girls-inspired music video for “Thank U, Next,“writing, “HUUUUUGE,” next to a photo of the pair in her “Burn Book” of her ex-lovers.

Davidson claimed that Grande decided to release “Thank U, Next” just minutes before an episode ofSNLaired because it had gotten back to Grande’s team that Davidson had made a comment about her during the dress rehearsal.

“Usually when you hear I said something about someone, you don’t think it’s going to be nice,” he continued, before adding that he was always planning on saying something nice about Grande.

Reps for Grande did not immediately return PEOPLE’s request for comment about the jokes.

Even after Grande released the song, in which she name-drops Davidson and other former flames, he still complimented his ex onSNL, calling her a “wonderful, strong person” and adding, “I genuinely wish her all the happiness in the world.”
