Someone who is drunk to the point of vomiting, but still has the sense to try to keep it in, thereby mouth vomiting chunks of food and bile that are now caught in the space between their cheek and gum. Recognizable signs of someone suffering from this condition are extreme perspiration, a look of intense worry, constant swallowing, and occasional burping. Slurred words often occur as well as diminished coordination.
"Dave was looking pretty squirrel faced right before he blew chunks all over Shannon."
"I saw Cindy all squirrel faced, running for the WC."
"I got a little squirrel faced yesterday when John fell into the septic tank at the party."
