I would say "fun" is the fact that you are attempting to make a Pack Pact. And by "fun" I mean "fun to say," and also "I am desperately uncool."
I will also admit to staring at this thread for approx. five minutes trying to remember if those two words are homophones, homologous or if they are another word I can't remember. The conclusion I have reached: it is time for me to go to bed.
