In summary, all the examples you provided are grammatically correct. They are in my opinion, more suited in written form- I don't hear them spoken often, but they are not unnatural. 1) "Condone" means to "approve of undesirable behaviour", so you can try "I do not condone abusive behaviour" or "If the public condone such actions, it will send a wrong message to repeat offenders". 2) "Gavel" … I tend to read it more than hear it (maybe to describe the action of a judge or an auctioneer). Rarely heard of outside of these limited circles. E.g. "The sounding of the gavel announced the sale of a painting at another record price". 3) "Put me down" for two dollars- again, a bit rare. I'll probably say "Two dollars" on the bet table and be done with it. E.g. "Put me down for another round- two dollars." 4) Delousing- The act of delousing is surprisingly common, I sometimes read about it in the papers about children getting deloused with a fine comb and medication. But for most cases, they are written (not spoken). E.g. "The prisoners were first shorn of all their bodily hair, before being sprayed with a delousing liquid." 5) (Blown away) in the blink of an eye- Again, quite used often in written form, rarely spoken about. E.g. "I was blown away by the spectacular view" or "The bow of the shockwave blew everything away in its path at an instant".
