Glasgow shower
n.— «When about to go out somewhere special for the evening my personal grooming consists of hacking at my face with the blunt Bic razor my wife keeps by the side of the bath for when the waxing business hasn’t quite done the trick, and three strategic squirts of Lynx “Africa” deodorant (a procedure known colloquially as a “Glasgow Shower”).» —“The law applies to Damian Green, too” by Rod Liddle Spectator (United Kingdom) Dec. 3, 2008.
