To porb is to mistype the word 'porn' into a search engine, see that the word 'porb' is listed on the Urban Dictionary, click on the link and read the definition, which ends with the words 'Now you are reading this.' A masterpiece by liferdown there, justly recognised with more than 9,000 thumbs up. The name comes from the fact that mopeds are apparently fun to ride but embarrassing to be seen on. The least attractive person that you would be willing to have sex with. To possess a fur saddle is to be cursed, or perhaps blessed in some eyes, by a covering of hair that travels all the way from the tailbone to the navel in a continuous pubic band.

This, as the definition explains, is a person who 'likes to have sex with someone dressed in a mascot-type costume'.

A furrbie, however, is perhaps too sympathetic. The 'furry' community вЂ“ adults who like to dress up as animals and enjoy themselves in various ways вЂ“ gets described extensively, and not very sympathetically, on the Urban Dictionary. Photograph: Sarah Lee for the Guardian furrbie It is, as jscilz explains: 'The act of mass texting a generic message to members of the opposite sex in hopes that a guaranteed hookup for the night will be established.' Getting multiple volunteers is a risk you will have to take. (In case you're not: it's telephoning someone urgently, usually late at night, in order to have sex with them.) Booty grazing is essentially the same thing given a more industrial approach. You're no doubt already familiar with the concept of a 'booty call'. Specially made beds with arm holes in them might be a more practical solution. 'It usually leads to wishing arms could be pulled off and then put back on afterwards,' says lilyrandall. When two people try any form of cuddling in the 'spoons' arrangement, the rear party invariably ends up with an 'awkward arm', which, wherever they put it, will be crushed beneath one body or the other. This describes conventional sex, for once, but of a kind that only occurs on anniversaries, birthdays and at Christmas.
