What are hot boots and cold boots?
In other words, "hot boots" are anything, be it an actual object, argument or other psychological device, used to convince someone to do something that s/he is scared to do (has "cold feet" about). Whereas "cold boots" is pretty much the reverse - anything, be it an actual object, argument or other psychological device, used to try and either extricate or at the very least calm down someone who *has* jumped into a situation feet-first only to find it "too hot to handle". Very often the person who was too scared to get into whatever situation it was, turns out to have been right in the first place, and giving them the cold-boots treatment is the only remedy for your own mistake of having given them the hot-boots treatment in the first place. The two concepts most often crop up in arguments between friends over a romantic relationship that one of them is either (a) not yet involved in, and too scared to start, or (b) has gotten involved in, found out that they were *right* to have been too scared to start but it's too late now as it's already started, and wants to try to find a way of reasoning themselves out of it again becuase they can't handle it: and it is the best mate that provides the warm- and cold-boots treatment successively and ill-advisedly ;-)
