Van me up, Scotty!
"Van" is the drunken mis-spelling of 'Ban', a common device used to literally tell people to go away or bluntly put, fook off in TTF Chat. By some, this has been taken in as a joke and a euphemism for sex upon the forum, much like 'ploughing' or 'porking'. "Vanning" also applies to this.
