shoulder dive 

When one places a miniature picnic table on the floor, lies next to it, and rolls until their shoulder crushes the picnic table. (The shoulder dive should take place in front of the small child that made the picnic table).
Reasons for the shoulder dive may include: wanting to feel big and strong, picnic tables piss you off, the small child was being a bitch and had it coming

Jamie: Jay, you so just laid down the shoulder dive on that kids picnic table.
Jay: Damn right I did.
