Definition of "looner"

Many looners are terrified of talking about it in case they might be accused of being pederasts. They fear that a psychologist would just label them as "sick."

1999, Katharine Gates, Deviant Desires: Incredibly Strange Sex

Looners (as they call themselves) can generally be divided into two categories, regardless of whether they prefer their balloon play with a partner or alone: poppers and non-poppers.
