Unless something is REALLY funny or unexpected, i personally don’t really laugh anyway. Especially with a meme or online post, my brain just kinda goes ‘ah thats funny’. This can happen just as easily after a joke has been explained, or if i have to look something up for context. Once i have the context my brain still goes ‘ah thats funny’ and now ive stimulated my curiousity AND my humor.

Not much history to support it either.

Boot was just a portmanteau of ‘bot foot’
