Hello! I find germans have quite interesting and funny metaphorical phrases, and I wanted to share a log on that. Right now I only have a couple, but I will be expanding.
"Ich bin blau." "Du bist blau."
Literally: "I am blue." "You are blue"
Meaning: "I am drunk." "You are drunk"
(I just find really funny that a color is related to that kind of situation).
"Ich glaub ich spinne."
Literally: "I think I spider."
Meaning: "I think I am going crazy."
(Imagine calling yourself a spider when you are stressed out).
