In all seriousness, this is one of the reasons I hate the term "Intentional Single Preference." It's just a bunch of long words and doesn't convey the seriousness of what a rushee is doing if she exercises this option. "Suicide" does. I'm sure that's how its use came about to begin with. "You're only putting down one sorority? That's social suicide!"
