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!

A grin for one of those moments where you say or do something that is so unbelievably dumb, the only thing you can do is grin in a ridiculous manner. Bear in mind, the said action is literally so fucking stupid, no normal grin can convey the amount of stupidity your brain just expressed. (i.e. The face you make when your brain has a severe case of the shits.)
Sam walked into her kitchen and saw her boyfriend butchering yet another cow on the table they ate dinner from. When he noticed the angry look she gave him, all he was capable of was a half-shitted grin. This was the third time this month.

The facial expression found on incompetent jackasses while they are experiencing some sick sense of accomplishment after performing an act of dumbfuckery. Usually this facial expression, performed among other people, is followed by the individual getting their fucking teeth knocked out.

Sometimes shit-eating grin.
(1) n. A shit eating grin is a very wide and, to the outside observer, stupid looking grin, usually showing smugness, self-satisfaction, or inner humor. The term is most often seen in the expression "Wipe that shit eating grin off your face!", usually said by the aforementioned outside observer. This observer-based definition makes "shit eating grin" the negative counterpart to "You look like the cat who ate the canary." While the two expressions describe the same grin, they have very different connotations. This definition has nothing to do with the term "shit eater".
(2) n. Someone donning a forced smile in an uncomfortable, embarassing, or compromising situation could be said to have a shit eating grin. Because an uncomfortable situation is much more closely related to "eating shit" than smugness, it is plausible to assume that this is the first definition, although far from the most common, and that the above definition is a result of drift from this one.
Both of these uses are documented in the Oxford English Dictionary no earlier than 1957.
