This is speaking of canid animals (members of the dog family; Canidae). A knot is basically a swelling of the Bulbus Glandis, a part of a canine's penis. The erectile tissue swells up during the climax of sexual intercourse and locks when it penetrates the female allowing it to inseminate into the female canine (probably because these canid animals miss when they hump the female so the semen will miss, I think).
Dirty Friend: "Lol. Look at that dog's knot. Now it's stuck with the female"
Other Friend: "You're disgusting. You're probably thinking about bestiality you furry freak."

(n) An item which prevents an individual from wearing skinny jeans (see: swagga;not to be confused with swagger{for obvious reasons}).
Try as I might, this knot continues to prevent me (an individual) from wearing this pair of skinny jeans to the upcoming Alanis Moresett concert. For shame, for I (also an individual) adamantly feel that said pair of jeans accentuates my most voluptuous features. I am more angry and unsatisfied than a fat bitch that gotta make a second trip to the "co'na sto'" because she ate her wallet on the way there.

When animals mate, specifically canines--I'm actually not sure about felines--the penis enlarges during climax and remains enlarged to the point where he is literally stuck inside the female for as long as it the mating process goes on.

This happens to ensure insemination, and the male can ejaculate several times before he is shrinks down small enough to unmount. This is used as a kink of sorts in hybrid / abo fanfictions.
