In fact I think the Maltese word 'jaqq' comes from the word 'yuck'. Note that the 'j' in Maltese has the sound of 'y' and 'q' is guttural.
"Pish tosh" (not "tush," which is indeed slang for the backside) is a very formal, stuffy, almost Edwardian way of saying "Nonsense!" or "No way!"
I don't know if you're familiar with the TV show Frasier, but Frasier Crane and his brother Niles were somewhat affected and grandiose - they always wore designer clothes, drank the finest wines, and attended the opera regularly. Of course, they didn't see themselves as anything but "regular." One day their father tried to explain to them that they were often a bit pretentious. "Pish tosh!" and "Poppycock!" were their replies, which only proved their dad's point.
Going back to one of your earlier posts, I see you said when we disgust something. The verb disgust doesn't work like that in English. You should say 'when something disgusts us' or 'when we are disgusted by something'.
