The other day, I heard "Embrace yourself!". Instead of "brace yourself". I think I prefer that version

Demo is used as an abbreviation for both demonstration and demolition. Usually it's pretty obvious which one is intended, but every time I hear someone say "demo" I try to imagine what kind of chaos would result if the wrong usage was assumed.

Had a coworker whose first language was not English. His English was good, but some coloquialisms went over his head. At one point, I had to explain the difference between a "butt dial" and a "booty call."

These are usually eggcorns

Anyway, there was once a joke on Friends, where - to massively paraphrase - Joey said 'the point is moo ... not even the cows care about it'. I sometimes use 'moo' instead of 'moot' just 'cos it amuses me.

He said "Ah Potato, Tomato. Doesn't matter". I burst out laughing, some guy actually tried to correct him on it.

Old timer's disease

Nip it in the butt.

It’s nip it in the bud, bud.

'Emails'. Except it's a mean laughter and I wish they would stop.

I imagine people are being told to have a seizure

Go watch some YouTube (channel: that’s a bad idea).
