8.
The act of placing ones head between a fat girl's thighs while she does jumpingjacks.
Dude, my heads killing me. Was there a storm last night? 'cause i swear i was struck by lightning, or did your mom slam her cottage cheese thighs on my head during a jumpingjack rampage? She must have thunderstruck me.

9.
One who has fallen victim to the internet prank of thunderstriking someone.

This prank is similar to a "Rick Roll," though instead of Rick Astley's "Never Gonna Give You Up" music video, the victim is linked to the music video of AC/DC's "Thunderstruck."

This meme originated in an X-fire conversation, when Shanghai_Factor invented it.
Pranker: This is the funniest Family Guy clip I've ever seen! *link*
Prankee: You bastard!
Pranker: HA! Thunderstruck!
