Get the O-O mug.A term coined by Michael Stevens of Vsauce, Boil-o is an invisible, undetectable, unverifiable/unfalsifiable substance that appears whenever things begin to boil. While, yes, the phenomenon of boiling is perfectly explained without Boil-o, Boil-o is still there.
Boil-o is used as an example of redundancy. If a phenomena is perfectly explained without something, why include the something?

Get the Boil-o mug.Slang for a man with such a small penis, he needs to use sex toys and/or invite his friends to simultaneously penetrate his girlfriend.
I couldn't believe Matt begged me to fuck his smoking hot girlfriend the other night, but then I saw what a No Solo Hole-O he is. And right before I came, she leaned in and told me she would meet me at my house in an hour.
