bucket baby
n.— «After about 10 days of 24/7 supervised nursing, physical restraints, and good drugs she finally took him…though we sure doubted often if she was going to work out. Would have been much easier for all to have put him on a bucket, but the TB racing industry frowns on “bucket babies” due to the non-performing reputation.» —“Re: question about orphan foals” by Pinkhouses1961 Usenet: rec.equestrian Mar. 25, 2004.
