A very painful experience where a guy, either alone with a group of at least 3 friends, takes a good amount of Icy Hot in there hand and applies it on there genitals, then you see who can stand it the longest before someone go try to get it off.
Being extremely cool or chill. Someone who is icychill is generally popular among they're peers. There are also many icychill posers. If a loser, dork, or nerd says that they are icychill, then that will make them even more uncool.

2.Oh my god that loser Dylan said he was icychill. Let's beat him up.
