look up any word, like muddin:
1.) Square pectorials that resemble something off the Wendy's value meal. Petorials tend to be groomed and tanned with oil but it is not uncommon to find ungroomed and oiled up burger pecs.

Pronounced - Pete-or-ials
Example 1.) Damn, did you see that guy over there? He has some greasy ass petorials. Reminded me of a burger I had the other day.
