Kowtex

The thin cotton padding underneath packaged steaks and other beef products that soak up the blood resembling that of a used feminine napkin.

It's a good thing that the butcher put a kowtex under that T-bone, else blood would've dripped everywhere.

blow burp

Is a burp that is done with your mouth closed. Usually your cheeks will expand. Then you can blow it onto someone's face at close range or directionally blow it across the table at someone for instance.

My step-brother was being a dick talking politics at the dinner table, so I loaded up a nasty blow burp and fired it across the table at him.
