A disparaging term for Internet Explorer, especially given its higher propensity towards a slow computer/webpage experience, increased chances of malware or even toolbar infestations, and even in some cases, a bad layout since there are certain web designers that stopped bothering to design for IE compatibility. Thus, anybody who willingly uses IE despite MUCH better alternatives being installed on the computer is an idiot, hence "Idiot Explorer".
Gus (calling): Hey, I was trying to open this website and it keeps freezing, and there's 5 toolbars and every site I opened seems to have a popup. What's going on?
Me: Gus, for Pete's sake... How many times have I told you to stop using Idiot Explorer?
