"That man is trash," writes one critic ... as others call it "karma."

Twitter went in on Tristan Thompson on Tuesday, after he was exposed for allegedly cheating on pregnant girlfriend Khloe Kardashian by TMZ.

First, the website posted video of the Cleveland Cavaliers player from October 2017 -- three months into Khloe's pregnancy -- cheating on Kardashian with two different women. He's seen making out with one of them and motorboating the other, as she grabs his crotch. TMZ also posted footage of him taking another woman to his hotel this past weekend.

Khloe is due any day now, posting a photo of her with Thompson on Monday with the caption, "We are ready whenever you are little mama."

After video and photos of Thompson allegedly stepping out on Kardashian started making headlines, fans took to social media to slam the basketball player for his actions. Some also brought his other baby mama, Jordan Craig, into the conversation and threw some shade towards Khloe as well. Thompson and Kardashian started dating around the time he broke up with Craig, who was pregnant at the time of the split.

On Khloe's Instagram, fans have been leaving supportive comments like, "Be strong for that baby Girl!" and "U are fortunate to have a loving and supportive family! Love ur baby and ur life!!"

On Twitter, it was a different story. Here are some of the most savage reactions so far:
