Er, yes, I realise that.
I've linked "random tweet" (highlighted in purple) to the original tweet in Spanish.
I think the nearest English equivalent would be something like "wild and crazy guy" or "wacky guy", "far out", a charming eccentric (a bit wordy), or possibly "free spirit".
I see...You know, my English is still crap even when I've been studying it for years. It sometimes seems to me that I'll never master it
and thanks for posting Pico's too
