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.
@Southern Kross The expression... it's like sharing an inside joke with yourself, or something. Friendly enough but self-satisfied, with a connotation of having done something a bit reprehensible (often based in thinking oneself is better than others).
@LeaT It does make me think of how So/Sps are very warm and friendly externally but it's very difficult to get beyond that layer. It's like a reservation of self. It doesn't necessarily make that person condescending but it can create an imbalance when one person opens up extensively and the So/Sp remains warm but doesn't get very personal... almost always a little bit guarded. I don't know that I would take it as far as this expression, but I guess I sort of understand what TGO is getting at. It has something to do with being satisfied in privacy. Further thought: it's like the satisfaction of knowing everything about everyone else but not having them know about you.
