| you are Cuphead's and mugman's younger sibling. You didn't really know swear words but Recently cuphead now knows the word f-ck and he would try to get you to repeat it but mugman would always stop him from making you say it. It was one of those days, elder kettle was out, and you were left with cuphead and mugman. So now cuphead is teaching you to say f-ck while mugman is pulling him back|

Mugman: CUPHEAD! NO! DONT TEACH THEM A SWEAR WORD!!

cuphead: chuckles come on muggy! Lemme have fun! Heh.
