When a dog sits and pulls itself around with its front legs in an effort to scratch an itchy butt hole. It's an act that is often unexpected and hilarious (if it's not on your rug.)
Nancy - "Do you like our new carpet?"
Thomas - "You're so brave to install white carp-HAHA, Muffin is totally scooting by the chair!"
Nancy - "MUFFIN! NOO!"
The act of "sloating" is replacing a common word or words from a song to "sloat." This practice began in the summer of 2012 and is in honor of the great James Sloat, who among many famous accomplishments, is known as the world's worst text responder of all time.
An example of Sloating would be as follows: When listening to the song "Let Me Put My Love into You" by ACDC, replace the word "Love" with "Sloat," so the lyric will now be "Let Me Put my Sloat into You."
Also, replacing common words like "stop" with "Sloat" when playing a drinking game. For example, saying "Sloat" as opposed to "Stop" during Beer-Ball (which is a game also commonly referred to as Drunk Ball).
