What is Umbrella Handle?
1.
A female is giving a man a handjob, when the penis gets hard enough, she squeezes the tip, causing it to spurt. If it does a somewhat vertical stream upwards, the woman has 'gripped the umbrella handle.'
Boy 1: She totally gave me a GREAT umbrella handle!
Boy 2: Dude, sick.
Girl 1: I think I gripped the umbrella handle amazing.
Girl 2: Yuck!
Girl 1: No, it was actually a good rush.
