Butt-o refers to the way a person smells. Typically, the smell is like feces or a very similar odor.
"Dude, you smell like shit! instead Dude, you smell like butt-o" "Did you wipe? You smell like poop. instead Did you wipe? You have butt-o" "Go take a shower I can smell your ass from here. instead Your butt-o is making my eyes water, go take a shower"

That moment during a meeting where everyone has been there for so long that people get loopy and off-topic, and nothing productive is going on. Especially applicable to meetings that go late into the night.
Person A: Dude, we are getting nothing done right now.
Person B: It passed butts o' clock a long time ago, trust me.
