The news headline says,
‘10,000-yen level 5G smartphones’ are coming soon.
The smartphone makers, whose businesses have been plummeting because of the new Coronavirus, are going to play the penis game.
This headline soon became a meme in Japan.
Here is the trick.
In Japanese, penis means ちんこ.
がちんこ勝負 means all-out war
(FYI: Google translate and DeepL can’t translate the sentence well. They both translate as a penis)
Even native speakers can be confused if they see a sentence like this:
Tomorrow, I and he will have a penis game.
Tomorrow, I and he will have an all-out war
Both translations are grammatically correct and perfectly natural, though. lol
