Not "bonding" with a knife or other such object. Example: "I have xxxxxx for sale. It's a really great yyyyy but I just haven't bonded with it/am not bonding with it." It could more people good if you actually could articulate why you don't like it. It's not too bad here but I see it used to sell a lot of very different items.
Also as someone mentioned, "Sebbie" or "Spydie" or any derivation like that. It goes into firearms and accessories also like, "Winny", "Remmy". "Leupy", etc. I now it's a small thing but it really get to me.
