look up any word, like timebomb:
 
1.
the quite obvious combination of the two words grundel and delicious, grundelicious. meaning that the grundel that you have just sampled is just simply delicious, scrumptious, luscious, or other wise stupendously tasting. Grundelicious can also be used to describe any other productions of the anatomical region known as the grundel, including but not limited to grundel gravy, grundel cakes, grundel juice and grundel butter.
His grundel tasted delicious, it was truly a grundelicious treat.

Kid 1: Wow that grundel gravy your mom used at Thanksgiving was great, truly grundelicious just like she promised it would be! Is it a home recipe?
Kid 2: Yeh do you want my mom to write it down so your mom can make it next year?
Kid 3: You guys are fucking sick, I'm outta here.

Its all about the cocktapus.
