"Random" Japanese.

One of the ten nerdiest things you can do is to want to learn and use Japanese for any sort of percieved chic, or 'show' factor. It's not chic, it's entirely the opposite. Anyone who dropped a word like 'kawaii' into real life conversation would be met with similar revulsion from me as would meet anyone who said the word 'lol'. They are both displays of that person losing touch, becoming entirely un-self concious, and slipping into some alternate geek reality.

It's little better using it on the internet, but there is more license to do so and less room for scorn because at least the internet already occupies that alternate geek reality.

A particular point I want to mention are indeed those -chan style suffixes. When a westerner uses one they're just being a cringeworthy Japophile, but what about when someone with a Japanese background uses one? Why do that? It's so in-your-face. Is it important for them to have a big arrow pointing at their ethnicity and culture? Are they bragging about being Japanese?

How ya doing, buddy?

I'm better than anyone else who thinks they dislike seeing random Japanese, because I haven't even bothered to have my browser support Japanese characters, and I just see a lot of rectangle blocks instead of chicken scratches.

There's nowhere I can't reach.
