A word used to describe something utterly disgusting, but with a comedic twist. It makes you gag, but it's fantastic. It's gagtastic.
Adam: Hey, you know that girl from the triple date last night?

Austin: Yea, she was sexy

Adam: Dude, she's got encopresis...

Austin: Wow...that's gagtastic

A word to describe eating something that tastes completely horrible just because it is good for you.
Gwen: What are you drinking?
Steph: A beet, spinach, and spirulina smoothie. It is completely gagtastic but I am going to look hot in my bikini this summer.

I find greek yogurt to be completely gagtastic, but there's so much protein in it I keep choking it down every day.
