A senior-ish colleague

(he's got a C in his title but he's a IT guy) 

 

has just replied to something 

 

"lol. KK"

 

Erm...

 

Have a word

 

making a leap here but consider telling him to dial down his tik tok whilst you’re about it 

I have no idea what KK stands for.  Does it mean he is a bit racist but not into joining clubs?

I assume what he meant was

Dear Sirs,

lol kk

Yours faithfully etc

 

Perhaps you may be overthinking this.
