Tipski
When you play just the tip with your lady friend.
That becky definitely seemed like she was Delta Foxtrot Tango, but she only let him play tipski.
tipsky
When a man gets a boner, and it pokes out the the top of their waistband. Sometimes referred to as a tip-slip. Brought about by Dan Avidan from Game Grumps in their Bloodborne playthrough.
I was talking to this really cute girl, then she looked down at my crotch and pointed out that I had a tipsky going on.
