Seedbombing 

When multiple guys drop "seed" or semen on a female. It can either be a planned event or spontaneous.

Rick: "Tyler, when is the seedbombing taking place this weekend at your mom's house?"
Tyler: "Go to Hell! Also she would like to know what you and the guys want to eat afterwards."
Rick: "Spaghetti. What a nice lady?!"

Seedbombing 

when an individual or group who throws, shoots, or slingshots pellets of dirt filled with seeds, often into empty or abandoned lots; usually part of an urban renewal project or event

Larry: Let's throw an awesome event where we eat, drink, and mingle in between seedbombing expeditions around the neighborhood!

Jim: Cool! Let's go buy some seed pellets and slingshots!

sledbombing 

Intentionally jumping into someone's sled just as they take off even though they expressly told you they did not want you as part of their current sled run, and then their run gets fucked up

We got all twisted up from my little brother sledbombing us and we ended up taking out that little kid
