I'll just talk to my fellow sliders, fix up the gear a bit, stalk groups etc.
This year i scared the living shit out of an entire group. I was just watching a girl that was in the group, she saw me watching her, and she stood behind her boyfriend. I just started clicking my fingers together, and slowly walked towards the group, and then suddenly slid about 10 feet right to the girls feet and started hitting my hands randomly around her feet and i had her screaming for a good 45 seconds, i stood up and snarled in her ear and clicked my fingers in her ear, when her boyfriend (Mr. ToughGuy) Turns around and said "lay off man" and i replied back with "why, am i laying ON her too much? are you getting jealous?" and then just walked away.
one of my favorite scares yet.
