A slang term used to describe a women's vagina. It originate's from the hit UK TV comedy 'Bo' Selecta!' and is suited to a generic European accent.
Also, if asked to show your 'potakian', a gesture is made with the mouth to show an inside view of a vagina being tongued ('licked out' etc). This is done by pinching the the top lip with one hand, and the bottom lip with the other. The top lip is then pulled up, the bottom down, and the tongue is then wiggled within the hole.
'Let me see your potakian!' (then followed by the mouth gesture)
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
