look up any word, like fleek:
 
1.
An overweight/obese person (typically female) who has an inelegant outward appearance. Also commonly seen with short curly hair.
Hey, check out that chick over there! There's a frump-chunk if I ever saw one!

Sorry sir, this is a strictly no frump-chunk zone. No amount of Axe body spray is going to divert my attention from your inelegant outward appearance.
