Sexyy Red had a witty response to Antonio Brown's tweet about her.

On Tuesday, the "Pound Town" rapper responded to the ex-NFL player by quoting his tweet, which said she "stank." She added a photo that showed a frontal cross-section of a normal human brain alongside one labeled "Advanced CTE."

Chronic Traumatic Encephalopathy (CTE) is a progressive degenerative disease affecting people who have suffered repeated concussions and traumatic brain injuries, per the Indiana University School of Medicine.

Under the photo comparison of the two brain models was a meme-like line drawing of someone wearing a football helmet, drooling, while trying to force a square into a circle-shaped hole.

The meme was the 25-year-old rapper's clapback to the former football player, nicknamed AB.

AB previously quoted a tweet by @blackannctable captioned, "Sexxyy Red knows real music." The post showed the yellow-haired rapper smoking and vibing to a rock song inside a vehicle.

In Brown's retweet, he added a wikiHow image of kids covering their noses with handkerchiefs. "Oooo b**** it stank" was written on the image. He also used the hashtag #CTESPN in his post.

Meanwhile, netizens shared their reactions to the online beef between the two personalities on X, formerly Twitter. Some lauded the rapper for her witty response.

"Yes, Sexyy, you COOKED!" one X user tweeted.

"Get it, Sexyy!" another stated.

"She ate," quipped another netizen.

"Sexyy red retweeting with a CTE meme to AB's post is something I did not expect to see. LMAO," a different commenter wrote.

"Sexyy cooked. Leave women alone! She was minding her own business," said someone else.

"I feel like this is an incredibly intelligent kind of humor. Shout out, Redd," opined another.

However, some seemingly joined in on AB's insult toward the rapper.

"She's so ugly," one netizen tweeted.

"She be out here thinking she's cute," wrote another.

"Her appearance didn't match her name. She is nothing sexy," claimed a different netizen.

"She looks like a homeless girl with money," opined someone else.

AB previously claimed he "got CTE" in a September 2023 tweet. He accompanied his post with a video clip of a woman with a split tongue licking his diamond-encrusted middle finger.

But in 2019, he told ESPN he was "all right."

"Nah. If I had CTE, I wouldn't be able to have this beautiful gym. I wouldn't be able to be creative. I wouldn't be able to communicate. He didn't hit me hard," he said of the infamous hit by then-Cincinnati Bengals' Vontaze Burfict that knocked him nearly unconscious.

"You know, I got up and walked off the field. We won the game. I was all right. You play the game long enough, everyone [gets] hit hard."
