yab lam Qut ghaj naDev vay'. chaq jIH ghaH.
Dirty mind may be an idiom that does not translate into Klingon; they may take it only literally ("What? You have dirt in your skull?").
I don't know you can combine pronouns to say jIH ghaH in the way that we can say I am he or I am she. Maybe.
There is the criminally underused word Qut, meaning "be vulgar". Of course, one can certainly ask oneself what passes for vulgarity among Klingons.
