/jp/ - Otaku Culture

I think it's kind of funny that because I use my Japanese mostly for video games, I've learned all these words for various types of attacks (反撃 挟撃 etc) while I don't know many words for trivial day to day stuff.
But my English is kind of the same.
RPGs have taught me words like pauldron, but just now I had to look it up to find the English word this (apparently they're called power strips).

But is this really a problem?
I have no plans on moving to Japan (or any English speaking country), I use both languages just to play video games, watch movies or lurk various websites. I like to travel (have yet to visit Japan) so I'd use the languages while abroad but as a tourist I'm sure I could get away with not knowing the word for power strip.
