flute
noun
1
the penis. Plays on the shape, informed by oral sex. Variations include 'flesh flute', 'living flute', ONE-HOLED FLUTE, SILENT FLUTE, SKIN FLUTE; also PINK OBOE; the sense compares with Romany haboia (a hautboy, an early oboe). There are arguable examples in A Midsummer Night's Dream, 1600 (or earlier) and Anthony and Cleopatra, 1606–7 of Shakespeare punning on 'flute' as 'penis'. In more general usage in the C18 UK, 1671.
