The sexiest cat in the world. Also known as Michael (Mike) Shinoda. She has the squishiest nose ever and is the sweetest animal. Wheezes. Obese. Dead.
Damn, honey, look at that cat! She is so not as cute as Booper.

I was late getting home tonight because some blue-haired booper in a buick century pulled out in front of my rig and I couldn't stop in time.

We would scare and tease the new kid daily until he would skip lunch entirely and hide. Whenever we were about to beat him up, he would start booping and beg us to just 'leave him alone or he's gonna bring a gun to school'.
