You would!

Erm! This is a bit tricky, as it involves animal husbandry and the breeding of sheep.

Emmerdale farm stuff I suppose, so here goes:

A tup is a male sheep. This noun lends itself to a verb.

Ewes that have successfully mated have a mark on their backs left by a a device fixed to a tup's belly.

This then lets a farmer know at a glance which ewes have, or haven't met the tup.
