LOL
I have seen numerous rants about people typing it - but my brother has taken this to the next, even more infuriating level.

He actually says "LOL" to indicate amusement (as a word, rather than an acronym). It has actually replaced genuine laughter in his repertoire of spoken word and sound.

...before he infects the others.

a colleague
has also been saying "lol" recently.

I'm afraid that the infected are already amongst us.

I tend to say 'obv'.

I'm such a knob
