What is ?^-1?
1.
The inverse (x^-1(to the -1 power)) of the question marks... this is rarely ever seen since the ^ key is so annoying to look for, unless you already know what it is. The actual meaning is not as well known; but it is easily either
1)coming from someone who in actuality has no questions
2)coming from someone who wants someone to ask them a question so they can look smart
3) coming from someone who really has absolutely no idea what's going on at all (like towlie)
