A "rieken" is when a person defecates in a manner that is either such a relief or is so pleasurable that they develop an erection.

Can be used as either a noun or a verb in some situations.
I had some really bad fish tacos for lunch that didn't sit well. My stomach started gurgling and I was stuck in a meeting. Luckily I was able to rush out during a break just in time. It was such a relief I pulled a total rieken.

The other night George almost broke the toilet with that fudge dragon he let loose... He was excited about it he pulled a full reiken.
