boss-eyed
»You boss-eyed old cow, you.» (Stage-Land. 58. 22.)
Uneducated young man.
Boss-eyed means squint-eyed or with one eye injured. Here it is probably the former, the expression alluding to a woman.
The term may be connected with the schoolboy slang word »boss» as in »boss a shot» = make a bad shot—in which case it would refer to imperfection of the vision, rather than to obliquity in the position of the eye.
