Mm. If you're in a dorm, there's pretty good odds someone has a blowdryer or fan you could maybe bum a use off for a bit. Maybe ask a RA equivalent or somethin'. If you're particularly desperate and you've got something to tie it to, a bit of rope, fishing line (buy it somewhere, though that may not be an option if you can't afford another drying cycle -- something to consider for the future), or daisy-chained belts can serve as an impromptu drying line.
If it's nice out (which, uh. Probably not, unless you're in a radically different time zone than me. Sun's probably not out, and that's what you need), you might be able to hunt down an empty bench or something to lay stuff on -- you'd have to flip 'em around every once in a while and you'd be hanging around for a fair amount of time, but it'd work. Railing is really good for that if you've got access to it.
E: But if y'don't have resources, y'don't have resources. Just... spread 'em out as much as possible -- get as much surface area exposed to air (preferably moving air) as you can. If you've got space, probably get those damper ones out of the hamper, and hang the better ones off something (bed, desk, whatever). Never really happened to me when I was in the dorms, but the last time I was back home and the dryer broke down I ended up hanging most of the load off a ladder and the rest off walking sticks* shoved in various places to keep things off the ground, just as an example. If there's a decent sized TV, you can probably hang a couple shirts or whatev' off that. Wherever you can fit something, basically.
*With fair note most of my walking sticks are just comfortably sized tree branches I've picked up over the years. There's probably a few of those laying around outside somewhere >_>
