Acronym for "kick the f*ing ball." Literally, something you would yell during a game of soccer to someone who is staring at an open goal with no defender in sight.

However, in a more general sense, it means that someone is staring at a golden opportunity that can be easily achieved and all they need to do is to KTFB and get an easy win.
In soccer:
Announcer: Messi passes the ball to Milito inside the penalty box and Robert Green is off to get some fish n chips! KTFB!!

In life, generally:
Mr. A: That girl is totally hitting on me!
Mr. B: KTFB!!

“I Know That Feel Bro” (also known as “to uczucie” or “to uczócie”) is an Internet slang expression used to convey empathy towards or agree with someone else’s feeling or opinion. The expression, which roughly means “I feel you, bro,” is typically accompanied by a contour- drawing reaction image of two bald men embracing each other expressionlessly. The face has been used as an exploitable character and is often seen in “that feel when” (TFW) threads on image boards, which describe an emotional situation or event.

It is said of the situation where a person has the bad luck to make contact with his testicles against an undefined surface or object, intentioned or not.
Given the nature of the word, it is more appropriate to design cases where the interaction is made with a moving object, for example, a ball.
Although it is extremely painful for the victim, it tends to be considerably funny to people who witness it.
