Sip slut
One who will take a sip of ANY of the drinks nearest to them. This person will not go get a drink of their own, instead they will reach over and grab yours while asking “can i have some?” Bat their eyelashes, smirk, pucker their lips and take a sip before the owner can respond!
Julie was so thirsty after smoking the joint, she reached over and grabbed my ginger ale without hesitation! Shes such a sip slut!
