I need to translate a childish insult "turbo-dweeb", and I'm a bit confused about the word "turbo".

There's a calque of "turbo" here in Russian. But if used as an insult, it sounds a bit outdated, like something said by a "cool kid" from the 90-th.

Does it have the same flavour in English, or is it neutral?
