Vocal
In the throes of a 3-hour musical bonding stint with some frightfully gifted corridormates, a weed tutored by veritable vocal Goliaths, I managed somehow to belt out a top C. Although "belt" is too flattering a verb, and in general my singing skills are not deservant of being described by such a powerful-sounding item of clothing; thus, I "socked" that high C, or perhaps "underweared" it.
Our singing made small metallic wall fixtures vibrate like dragonflies.
