The fear of having a Big Mac attack and not being able to sexually satisfy the Big Mac. So you wonder if there is even any point in puting a condem on if the Big Mac is just going to lay there like a dead fish. I mean come on, where both adults here, if you don't want to be here then we should just call it off right now.....
I Love you Big Mac.
Jim looked up from his Fillet-O-Fish with longful eyes as Grimace finished off his Big Mac. Jim had never eaten a Big Mac for fear of suffering from Big-Mac-attack-o-phobia
