Feel threads are the worst/best thing about /mu/, as illustrated in many /q/ threads with multiple faggots stating "keep feel threads on /mu/!" and "get the feel threads off of /mu/!". Feel thread defenders argue that "feel threads are the best thing about /mu/. Where else am I supposed to go to express my gushing betafag teenager emotions?". Feel thread haters argue that "feel threads are off-topic, annoying, spam, and detract from what /mu/ is all about".
People on /q/ came up with the solution, asking why don't /mu/tants simply just feel on /r9k/, but /mutants/ kindly explained that they don't wanna feel on /r9k/, probably because people from /r9k/ smell bad or something.
After much debate, nothing much has been done to feel threads, except maybe contain them into one thread.
There also exists an official last.fm That Feel group, inhabited by /mu/tants. Its denizens have dubbed it "/that+feel/", attributed to its appearance in the browser address bar. The group was originally made to lessen the quantity of feel threads on /mu/, which ironically its creator would spam on /mu/ 20 hours a day.
The Feel Guy
The feel guy is an iconic image that /mu/tants worship like a golden cow even though it's just a poorly-drawn MSpaint image of a guy with cancer.
