"guchhies"? "UN yelling"?
Anyway, I haven't yet seen underwear that is truly seamed like bike shorts; their panels almost always meet at the 'taint, right where you'd sit on them on a bike saddle. I have some spandex boxer briefs that used to be sold at Target that are about as seamless as you'll find, and Under Armour briefs are pretty close.
I'll keep watching this thread myself for some better options.
