A term most commonly used amongst the sexually active elderly to describe a
gentleman who’s pubic hair has gone white,
long and untamed - completely hiding his penis, visually resembling the tail of a lamb. He gives his lady one pump in her front door and one pump in her back door (two shakes) before losing his erection and calling it a
night. His lady is less than satisfied, but it’s better than nothing.
“
Bernie, are you and Irene coming to
bingo?”
“No, I’ve gotta get this bitch
home to give her Two Shakes of a Lamb’s Tail. See you next week, if we’re not dead yet.”
