vest: aka tank top t-shirt: aka wife-beater.
Usually seen because McClane gets so beat up throughout the course of the movie any regular shirt he is wearing at the beginning gets too mangled to wear by halfway through the movie.

The star of Die Hard, and anyone wearing a vest!
When you say John McClane, you should roll up your sleeves to symbolise a vest!

When you enter "the zone" in a video game and begin killing enemies at will. Seeming to be untouchable and indestructible.

Taken from the Die Hard movies where the Bruce Willis character of John McClane seems to kill at will without getting hurt.
Leroy Jenkems was killing guys left and right and then went all John McClane on them and took over the match.

We were loosing the match but MOB4LIFE gave them "The John McClane" move and killed everybody.
