Nummy is a cooler way of saying
awkward. You can also express the feeling of awkwardness with "nums" for short. No, nummy does not
mean "tasty," as you might think. It is nummy that
people think that...
"That
kid thinks nummy means yummy"
"Nummy, breh!
"
Wow, didn't those two just break up, but now they're best
friends?"
"Totally nums breh!"
