Literal translation of the word シレジレ

Question

I'm not sure how to translate the word シレジレ.

Does it mean something like "perky, confident, opinionated, presumptuous"?

If so, may シレジレメカコラム be translated as "All-knowing Mecha Column" or "Wise Guy's Mecha Column"?

Entry for 痴れ痴れ on Weblio: 「いかにもとぼけたさま」 == "looking extremely stupid [possibly intentionally]". I don't think you want that one either. とぼける can mean to play the fool, i.e. to play dumb while actually being smart, or to dissemble, to feign ignorance, such as when asked about something, but it can also mean to be vacant, absentminded and to go senile, as with old age.

The シレ in 痴{し}れ痴{じ}れ is from verb 痴{し}れる, which (confusingly) kinda means the opposite of 知{し}れる. Main definition for 痴れる in my copy of Shogakukan:

• 「判断{はんだん}・識別{しきべつ}の能力{のうりょく}が働{はたら}かなくなる。ぼける。ばかになる。」
  To lose one's ability to make judgments or distinguish. To become senile or dotty. To become stupid or foolish.

As suggested by 非回答者's ignorance of the term, it's probably not used very commonly in mainstream Japanese. The katakana spelling only gets 162 Google hits, actually collapsing to just 38 hits if you click Next a few times. The kanji spelling gets 677 hits, collapsing to just 109 hits if you click Next enough, of which the first page is all dictionary sites, and a number of the hits on the next two pages are of sites explaining the term.

If you're trying to come up with a column title, this might not be the word to use. If instead シレジレメカコラム is something you found and you're wondering what it means, my rough guess would be "goofy mecha column", with an emphasis on the "ditzy" shades of meaning in "goofy" (some of the Google image results for just 痴れ suggest "ditzy" in feminine ways; various images are NSFW, so I'll leave that as an exercise for the reader). Without more context, though, that's just a shot-in-the-dark guess.
