After using a urinal you're permitted to remove any excess urine off by shaking your cock twice. Three times you're just having a wank.
It's occasionally difficult to tell if people are simply ignorant of the three shake rule or if half the population of galway are chronic masturbators.

An amendment to the constitution of dong handling. Previously, the constitution stated that shaking your tallywhacker more than twice after taking a piss would be deemed "playing with it". The third shake clause permits the man pissing to give an additional shake to his dong, in order to ensure minimal dribble.
"No sir, I was not playing with myself, I was simply exercising the constitutional rights handed down by my forefathers. Third shake clause beeitch! Get out ma business!

A person uses a shake weight about chest high in front of their body. The weight is tilted slightly back pointed towards their face. After a short time motioning the weight up and down another person pours a shot into into the users mouth. Preferably something white and/or creamy like Baileys Irish Cream.
Wow my girlfriend did a shake weight shot at a party last night!
What's that?

"Where's Tom?", I asked. "He's shaking hands with the mayor", my sister answered as she gestured towards the men's room.
