To feel up a girl when she isn't expecting it, that is, grasp her tits or grab her in the crotch (and if a finger shud happen to enter her vagina, so much the better !!)
Best time to cop a feel is in a crowded place so you can run off and can't be found. When I went to my family reunion my 3rd cousin once removed was in a crowd and her juicy peaches were calling me, so I ran up, coped a feel and ran away to the punch table 2 aisles over. Later in the day I grabbed her crotch and my middle finger just happened to slip into her cunt.
