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!"
