Glad to see this old favourite appear on the Mudcat. You should however beware of believing that the sexual connotation of 'gay' is modern -- it isn't. In low use it used to mean 'randy' or 'promiscuous'. 'Gaying pintle' was the male member and 'gay' as a verb simply meant to 'fornicate'. The Victorian whores' come-on was 'Are you gay?' and, until the early 20th Century prostitutes were referred to as 'gay women'.
Nevertheless, enjoy your roly-poly!
