"to form a loop," c. 1400, "draw (a leash through a ring)," from loop (n.). Related: Looped; looping. Slang looped "drunk" is from 1934. Loop the loop (1900) originally was in reference to roller-coasters at amusement parks.

"Loop-the-Loop" is the name of a new entertainment which goes further in the way of tempting Providence than anything yet invented. The "Loop" is an immense circle of track in the air. A car on a mimic railway shoots down a very steep incline, and is impelled around the inner side of this loop. ... The authorities at Coney Island are said to have prohibited "looping-the-loop" because women break their corset strings in their efforts to catch their breath as they sweep down the incline, and moreover, a young man is reported to have ruptured a blood vessel in his liver.
