If you can admit to PMSL at a lolcat while eating al desko alongside the subject of your man crush, who has a mahoosive digital footprint, you are using several new terms added to a dictionary website today.
A slew of social media or gaming terms and abbreviations that will leave your mates either well jel or asking WTAF are included in the latest and so far largest quarterly update to OxfordDictionaries.com.
Also among the 1,000 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.
Judy Pearsall, editorial director for Oxford Dictionaries, said: "One of the benefits of our unique language monitoring programme is that it enables us to track in detail how English language evolves over relatively short periods of time.
"For instance, in this age of the selfie perhaps it's no surprise that average monthly usage of the term duckface is 35 per cent higher in 2014 than it was last year."
Many of the terms may be undecipherable by anyone born before 1990: PMSL stands for "p****** myself laughing" at something very amusing, 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. A lolcat is a funny internet video of a cat.
Jel is short for jealous and WTAF is "What the actual f***" posed as a questioning exclamation.
There are also business terms like "crony capitalism" and food references like the "five second rule", the apocryphal time between dropping food on the floor and it becoming too full of bacteria to pick up and eat.
Other new terms include 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.
