WE HAVE NOT BEEN OVERWHELMED with New Year's resolutions from the teen front. Nor have we been deluged with slang that, when translated, means "wholesome food" or "a new face-cleansing regimen" or a "bedroom without mounds of clothes on the floor." On the contrary, teen-agers are too busy entrenching bad habits to think about reforming them. Consider some of these new expressions: lost in the sauce colloq. Out of it, as in "There's a boy in my class who never understands what's going on, and the teacher always catches him lost in the sauce" (Nathan Masson, Lanham). smit v. To skip school or to skip a class, as in "Trig is so boring. I think we ought to smit" (Carrie Stevens and Dawn Ortowski, Damascus High School). splockenin' v. Egging, particularly an enemy's car or house, as in "Last night Greg and Johnny went splockenin'. They got Lisa's house good" (Kelly Pawlik, Fredericksburg, Va.).

And then there is this, the Word of the Month, from Cherish Lorson of Woodbridge: bus head n. After a very long trip for a school-related activity, when everyone gets off the bus and their hair is sticking up all over the place, you say that they have bus head. Linguistic observers are invited to send examples of teen-age slang to: J Street, The Washington Post Magazine, 1150 15th St. NW, Washington, D.C. 20071.
