The most prevalently-used and virus-susceptible email client in the history of computing. Frequently euphemized as Outlook Express.
When I installed SP2, Outhouse Express presumed to decide for me whether to download the images in my email.

Mail client inferior to Thunderbird, Opera, KMail, etc.
If you personified Outhouse Express and Idiot Exploiter, I'm sure the two would enjoy anal with each other.

A piece of software that makes the British Postal Service look efficient.
I was going to send an email today, but Outhouse Express deleted them most of my email, moved everything else to it's wanky proprietary folder and forgot my password. It is a steaming piece of shit.
