"Tic off" or "Tick off"?

Which is correct (not in reference to removing an insect)? Thank you!

In the UK the phrase "to tic off" is used when filling out a form - using check or "tic" marks, and only in that sense. "Let's tic off bullet points 3 through 7, we've covered those", or "Darling, tic off bread, milk, and catfood from the grocery list, I picked them up on the way home from work".
"Ticked off" is the standard US spelling for that usage, and is the universally accepted spelling for the sensation of controlled anger, e.g. "Boy, they ticked me off in that meeting,glossing over points 3 through 7", "Darling, I was really ticked off at the checker when I stopped to buy bread, milk, and catfood on my way home from work".

I'm afraid that's not correct.

In BrE, the only meaning of "tic" is a habitual spasmodic contraction of the muscles, most often in the face.

In BrE, "tick" has several meanings, including when you tick a box; a parasite; getting something on credit; the sound of a clock, and being annoyed (ticked off, though it is an Americanism that is widely understood, but not commonly used).

I think AmE and other variants are the same.
