A mid-tier level of inebriated, drunk, intoxicated while in a positive, fun, state of mind (not rowdy, sloppy or mean). Definitely more drunk than a buzz but not enough to get kicked out of the function.
The word shmeefed is used to describe the level of ones high. There is sober, high, boofed, booted and zooted, and the ultimate high completion is considered as shmeefed.
