A personal story - when talking to my friend (Sean) ....
Me: Dude, the weather is so hot today. I wanna go and get some soft drink. What do you want? My treat.
Sean: Cool bro, I want "cow-piss". Thanks !
Me: What ??!!!
Sean: "cow-piss" bro, "COW-PISS".
Me: (Disbelief, and witholding my disappointment) Dude, what the heck is that? Show me a picture....
Sean: Wait, let me Google it...
Sean whips out his smartphone and came up with the picture below within a few seconds
- Lesson learnt - ask that person to send you a picture of the item if you cannot understand what they are talking about
