a. Very nice tasting food or drink: 'The food was nomshus'
b. Compliment: 'You look nomshus!'
( Form the phrase 'To nom' as in to eat or chew. After 'nomming' the 'nommer' would show their reaction to the substance that had been 'nommed' by either stating that it wasn't nice or alternatively that it was very nice or "Nomshus"! )
I just had that triple fudge toffee caramel cake, nomshus to the max!
