Our mind works weirdly

There's a vowel in LOL, makes it easier to say as one word.

@naughtybear says “lol” during verbal conversation...
is that a sign of something

Wtf refers to a commonly used phrase, what the fuck, while lol is an expression of laughter more than a phrase. That's why we translate wtf into words but not lol.

In my head 'wtf" sounds like "WhTuhFuh'

Thank God the post censored the word fuck. This is a wholesome Christian site.
