When someone begins arse licking another person (figuratively) who then begins to arse lick them back so as to provoke further arse licking from the first party. May result in a tear in the fabric of space and time if the circle is large enough.
Harley: Wow I love hanging around with lower sixth so much they think i'm a god. I best hang around with them more so they worship me more
Lower sixth pleb: Wow harley is so cool hanging roud with us lower sixth plebians, we best keep worshipping him so he doesn't leave us
All: Oh for shame, we have created a vicious circle of arse lickery and now the universe as we know it will cease to exist.
