The beauty of these words is their compositionability(?). “Mon hostie de calice de tabarnak m’a t’en crissé une” is a great example of using these words as nouns, adjectives and verbs. They can even be adverbs (calice, calicer, calicement, criss, crisser, crissement, etc.)

On their own they’re not really insult though.

Also disliking “those guys” as a generalised statement is a pretty racist statement, ironically.
