(adv.) an overt display of self-satisfied smugness when clearly such displays are either undeserved or unwarranted. As if the subject were to smile innocently only to reveal a mouthful of shit to his/her peers.
Kyle: "Did you see that shit-grinning bastard John after he got his paper back?"
Whitt: "Yea he looked like a gloating douche for sure"
A grin given by the grinner to show or perhaps hide an inside thought or observation of their surroundings. The grin is usually obvious and not containable but more likely the grinner does not want to contain the grin therefore getting their point across without speaking. Sometimes you just can't say things with words so don a shit grin instead!
