look up any word, like eiffel tower:
Originating in the late 90s outdoor party scene in the area surrounding Shrewsbury, West Shropshire the Shrewsbury Finger is when the index finger is wagged vociferously in both recognition and appreciation of a 'bangin tune' slipped in by a DJ usually specialising in drum 'n' bass, breaks or techno.

"Nafe's givin' it the Shrewsbury Finger to this tune!"
