Cockswoggling 

I'd like to coin a new phrase -
Cockswoggling -- when a guy shakes another guys hand and tries to dominate him to show he's the cock of the cage by squashing his hand or yanking him towards himself or not letting go until he says it's time.
Cockswoggling.
You're welcome.

I'm afraid to shake Donald Trump's hand - he'll yank you in - grab on tight and won't let go until he's good and ready. He's known for his cockswoggling!
