noun

The penis. · A term of abuse.

Selected source glosses provide context, not a complete modern definition inventory

Originally northern British usage, from the 1960s. Probably the simple use of a proper name as a pet name; compare dick, fanny and peter. Unlikely to be a contraction of Latin membrum virile, male member (that is, the penis), a Latin term used in English in the 19th century.
