⚠️swear warning⚠️

Regularly says f*ck:
Red, Error, Viper, X!Gaster, Nightmare, Dust, Fell, Me

Has sworn of saying f*ck, but said it at some point:
Dance, Yanberry, Sans, Handplates!Gaster, Geno, Pup

Has not said f*ck before, but can if desired:
Blue, Glitchtale!Gaster, Outer, Dream, Ink, Killer, Horror, Carrot, Fresh (when he's hella angry)

Has not said f*ck before and refuses to do so:
Papyrus

Legally can't say f*ck:
No one I'm aware off, so far

Bonus
Doesn't say f*ck out loud, but 24/7 inside their head:
Sci, Cross, Westy

Fun fact:
-Red/Edge is really moody but is a lot calmer when around Sci :D. -Yanberry used to hate Sci, but he learned some valuables lessons from him and became his friend.
-Sci is Error's favourite Sans. (Error: C̸͟͞R̸͟͞E̸͟͞A̸͟͞T̸͟͞O̸͟͞R̸͟͞! W̸͟͞H̸͟͞A̸͟͞T̸͟͞ T̸͟͞H̸͟͞E̸͟͞ F̸͟͞U̸͟͞N̸͟͞K̸͟͞?!)
-Sci doesn't hate Fresh, but is annoyed by him a lot of times.

Aight, that's everyone who came into my mind, might update it at some point.
