Yet another creative extemporisation of LOL.

Typically surreptitiously used as a greeting to individuals unaware of the disturbing world of internet chat subculture.

After said usage, one often thinks to one's self "lol".

What the hell + lol = what the hellol.

Can be used if someone.

1 does something so stupid that, even though it pisses you off, it actually makes you laugh.

2 When someone says something funny randomly.

3 Used when someone says something that puts you in a state of shock, and laughter.

Can be considered a replacement for lolwut
