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.”
