Thunder Fist 

A Thunder Fist is the moment when, during a storm, the thunder hits you so loudly that you feel like you were just punched in the ear.

John: Man, that storm last night was awful!
Dave: Yeah, I definitely hid in the bathroom as soon as the thunder fist hit me.

thunder thighs

Basically, you have normal thighs, then they get fat (tier 1). But when they get like even fatter, you get another level of fat like a hill of fat(tier 2), which is loose off the other fat so when a thunder thigh is being walked besides the legs (tier 1) rubbing against eachother they (tier 2) hit eachother making a noise, hence thunder coming into the expression, most likely to because of alliteration for a dramatic, comedic affect. This sound can have a brighter tone and richer feel if accentuated with bumpy cellulite
