How do I tell them without sounding offensive?

Help me out, oh wise Mumsnetters!

Someone I know has been unknowingly - I think! - and repeatedly using a derogatory term when referring to someone else, and it makes me cringe every time I see it happen (these incidents are happening online). I don't think this person has bad intentions, and I know I'd want to be told if it were me making the same mistake, so I'd like to send them a quick message - but how to word it without sounding offensive?! I want to tread carefully, this person and I have interacted before but we're not best friends.

Should I say something - and, if so, what and how? - or should I stay out of it? What say you, Mumsnet?!

Christ - I don't really think you need to agonise over this, it's such a non issue. Anyone else would read it as a simple mistake, and if they knew the meaning of the word possibly raise half a smile....

My Mum text me when she had a massive heart attack saying:

'Had huge heart attack- in intensive care. LOL Mum x'

Obviously she intended it to mean lots of love as a lot of people use it as such, but it did make me laugh at what was otherwise a stressful time.

Just let it go.

Well I've learned something new today. I'm a millennial and had never heard of 'Thot'. (Which my phone just autocorrected to Thor 3 times in a row!)
