High Hat 

Used in conversation when remarking that someone thinks they are funny or are being a smart-aleck.

Taken from the sound that is made when the snare drum and high hat are hit in sequence after the punch line of a joke.

John: Hey I stopped by the house and picked up your mail. Do you want me to put in my box?

Chris: That's what she said!

John: There you go again. Always coming with the "High Hat". Cant you ever take things seriously?

High blood pressure titties 

When a woman has really huge breasts and a huge body to match, it usually means she has high blood pressure due to all the added weight. These women are generally very good cooks and like to eat even more.

Louise Jefferson from The Jeffersons had some really big high blood pressure titties
