2. A punch in boxing that knocks your opponent unconscious, typically ending the match.

A sexy transformer who likes the way he looks in steel-belted radials. He attempted to join the Autobots in the television series Transformers - Prime on the last episode only to be rejected, but in the movie he was accepted. Knock Out is very concerned about keeping his finish clean and his paint looking fabulous.
Knock Out is not only an automobile, but an automobile enthusiast.

Knockout is a forum that sprung from the remains of Facepunch in early 2018, and has since eclipsed Facepunch tenfold to become a seething hive of degeneracy with fetishes that would make /b/ scream in horror before reaching for the bleach.

Most of Knockout's demographic are thirty-something year olds who were hot stuff when Facepunch hit its prime in late 2010, and are now stuck whining about how they wasted all their life experiences by being shut-ins in their mother's basements or boozing for years but can't work up the will to either stop posting or administer nine grams of lead to their brain.

When Knockouters aren't busy explaining their fucked up fetishes, torrenting child porn, or treating tiny pixels next to their names like Viagra for their penises irl, they spend their days like ResetERA does: whining about anything that doesn't fit the social justice definition, whining about representation, whining about how no one takes them seriously, and whining at each other like the bitches they are, but if you try to point out that their lives are worthless and that they have better things to get upset over, they will cry like pussies and bombard you with "Dumb" ratings. Meanwhile you can get banned for not going along with the community or whenever the jannies wish.

Knockout is hell.
Rick: Dude, what the fuck? Some idiot on a forum just told me that he watched CP and fapped to it.
Dave: Oh, what site was this?
Rick: Knockout, of course.

Inacio: I know, I'll make a forum to replace Facepunch!
Creepy Knockout members: Can we join too...
Inacio: Yeah, sure, come in- OH SWEET JESUS FUCK
