When you think you are hidden behind an object but someone can clearly see the top of your head poking over it. The term is more widely used in video games where you are unaware of your players model and therefore have no idea your head is sticking out.

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

A term used to describe a person that is extra ordinary in seeking the truth in a humorous way. A person said to be a "Thunder Cat" is one of street smarts, wise to the ways of doing things, and can quickly unmask untruths.
