Noun

1. A stallion, especially in the sense of mount.

   The studded bridle on a ragged bough

   Nimbly she fastens: -- O, how quick is love! --

   The steed is stalled up, and even now

   To tie the rider she begins to prove:

   Backward she push'd him, as she would be thrust,

   And govern'd him in strength, though not in lust. — Shakespeare, "Venus and Adonis".
