Mahoosive mamils admitted to Oxford

Lolocat, well jel, man crush and mahoosive are likely to be meaningless to anyone born before 1990 but they are among the 1000 new words added to OxfordDictionaries.com, the free online dictionary, in its largest quarterly update.

The entries by editors at Oxford Dictionaries reflect the influence of popular culture, or teenspeak, and include abbreviations such as WTAF (what the actual f***), lolcat (a picture of a cat with a humorous caption), IDC (I don't care) and PMSL (p****** myself laughing).

Words from gaming terminology include respawn (a character in a video game who reappears after dying) and permadeath (one who does not reappear).

Also among the new entries is duckface, the pouting lip-thrusting face pulled by people posing for photographs, and mamil, an acronym for "middle-aged man in lycra" sparked by the increasing popularity of sport cycling.

Al desko is an act, usually eating, carried out at a desk; a man crush is non-sexual bonding between two men, mahoosive means very large and a digital footprint is how popular someone is online.

Jel is short for jealous.

Business terms include "crony capitalism".

The "five-second rule" is the apocryphal time between dropping food on the floor and it becoming too full of bacteria to pick up and eat.

Other new terms are fone, a misspelling of phone, tiki-taka, a style of aesthetically pleasing football made popular by Barcelona, and shabby chic, a piece of clothing or furniture deliberately aged for fashion reasons.

Last month, Oxford Dictionaries announced vape as its international word of the year, reflecting the meteoric rise in popularity - and scrutiny - of electronic cigarettes.
