a lot of maltese swearing centres around making completely random sentences involving the words snake, vagina and semen. sometimes they don't even make sense when you think about it, something like "żobb f'oxx il-liba" would be "acceptable" even though that just means "a snake in the semen's vagina", and I've even heard "żobb ġo bott" (snake in a jar) a couple times too
edit: oh and there's this weird word "pufta" which basically means gay dude, the weird thing is tho I heard it in a Monty Python sketch, what?
though my favourite is still daemagen from muh own conlang because im cool
