I don't find it offensive, but it does seem most other people do. So I would say its probably one of the worst. I find the use of it pretty satisfying when the person is really pissing me off, so i guess that in itself says how strong a word it is tbh. I do find it a bit..misogynistic how one of the most offensive words is a slag term for womens bits mind, but I still do use it myself so
