So it seems like the grammatically correct way to go about tacking things onto the name would be to have the Frost*erisk always and ever come right after the word Frost*. They are one entity. Always.
Frost*'s
Frost*erisk
Frost*ies
Frost*iness
Frost*alongadingdong
And the like.
P.S lol, F***er's
P.P.S Most Frost*erisks ever.
