Its when you fuck someone so hard, that the impact of your bodies against each others makes a loud thunderous sound
Timmy: Suzy and I thunder banged last night and the neighbors got freaked out, they thought there was a storm coming.
Ben: THAT LOUD NOISE WAS YOU TWO?

An idiotic, immature, egotistical git who likes to backstab her "best-friend". She also likes to have sexual intercourse with boys who are missing teeth. Then, she likes to run her mouth and talk complete nonsence when she knows that the person she's talking about could whoop her ass.
Ex.
The "best-friend": Wow. My best friend, who isn't even friends with my boyfriend, tried to ruin our relationship by telling him that I was going to cheat on him, when she knew for a face that I'd never do that.
Another friend: What a Toothless Banging Thunder Cunt.
