To hound or pursue something or someone with a usually malicious intent.
Derived from the use of a bird dog to hunt
game.
Apparently mistaken by millennials as a slang hybrid of 'bird' being female, and 'dogging' being the act of cuckolding or sharing of
one's
wife willingly or unwillingly, whilst obviously overlooking the actual
normal every day meaning of the term to the point it irritated me to make a bloody account on here to set things straight. So upvote this definition so these low life tweens can at least use the term correctly.
