When you feel compelled to destroy something you have built up. (i'm sure there's some technical term for it)
Like, when you go to the beach and you build a sandcastle. The best part about building a sandcastle is jumping on it and watching in sink into the sea.
-Celia grew her nails and then bit them all off! Boy did it feel good.
-Mary grew her hair really really long then cut it all off! She was so happy.
-Janice wrote an entire novel on paper then threw it in the fire. What a laugh.
All these people are enjoying the sandcastle complex.
When you are on the beach with your lover and decide to build a sandcastle and put your penis through the tower windows and proceed to f**k her but just before you ejaculate, you pull out and release your sperm on the highest tower of the castle and let it ooze down.
Jack: Hey man, me and Sasha just got back from the beach.
Larry: Cool did you do it?
Jack: Do What
Larry: The dirty sandcastle
Jack:Oh yeah I did. I ended up flooding the moat and destroying the draw bridge.
Larry: Wow that's crazy
Tailgaters at a beach basically. The people at the beach that bring enough crap to hand out an item to every single person at the beach. They bring so many electronics that they could use the power from them to run a small city for a week and the tent they have looks like a midget circus is performing on the beach and can be seen from four and a half miles away. The food they bring looks like a catering service has been hired and usually ends up mostly uneaten.
Jimmy: Look at that jackass sandgater; it looks like he robbed a damn Publix.
Neil: WTF Jimmy, your right, that sandgater looks like he's building a new town.
