Like the term 'high-five', you give your fellow friend a high-five, but instead of your hands, it utilises the tip of your elbow (known as a wenus). Great to attract unwanted looks and attention when said in unison. Too much exertion can result in painful funnybones.
1: "Hey! Wenus five!"
2: "Wenus five! Awesome!"
1 & 2: *Laugh*
3 (onlooker): *eyebrows raised* Hmm.
