nosebreaker
n.— «I have been doing “nosebreakers” (AKA skullcrushers—great names for this exercise…), dips, and close grip bench press for my TRIs and it seems that my inner tris (higher up in the back of my arm) are growing at a great pace, but the outer tris aren’t responding much.» —“Triceps Exercises” by Luther Miller Usenet: misc.fitness July 23, 1992.
