Hands up in the air and yells "Party all the time"
She dance around me in her thong, sing along, favorite song

Meaning

Party girls are often caught yelling “party all the time” whilst they are intoxicated; more recently the phrase has evolved into “I’m Shmacked.” The founders of I’m Shmacked, DJ Carnage, and many others are convinced it’s a movement. Here’s an Instagram video that I’m Shmacked posted from USC.
