The word can have swearing but not genderisation which might be offensive (mother) nor allusions to sexual dominance (motherfucker). Nor, other possibly offensive connotations. It seems that the word is commonplace and people won’t stop using it, so an alternative to the word may be useful. But the problem with alternatives, is that people might not use them unless they carry a meaning that’s attention grabbing in some way, and when it comes to this word it needs to be able to be used in either a serious (non-funny) or comedic way.
I’m good with sticking with plain old motherfucker and have absolutely zero intention of replacing it with some convoluted bullshit alternative. I figure if he/she/it/they/them are offended by my use of the word motherfucker then it’s aimed at he/she/it/they/them anyway and all those motherfuckers can get fucked and stay fucked. Tired of catering to everyone’s sensibilities. Grow a pair, or a twat, put on your grown up panties and get the fuck over it.
