Is this normally said in German? Is this a cultural thing I'm not aware of?
Or maybe cups are falling from the window of the second flour! And a man shouts "Tassen!" to inform children below!
I don't think it's an idiomatic expression or anything of the sort, just something that might occur in everyday conversation. For example: "Should I bring cups or glasses for the punch?" "Cups!"
Perhaps someone is yelling for cups as a doctor would yell, "Scalpel!"
Maybe it's what they say in bars to the bartender.
I'M REALLY EXCITED ABOUT CUPS!
"omg giant man eating cups outside!!!!!!!!!" "giant what?" "CUPS!!!!!!!!!!"
Is this used like 'cheers' is or something?
