When people put 'epic' infront of things like 'epic fail', 'epic LOL', 'epic win'.
Also, the term 'hench' for a strong person, never heard this until I came to uni in Staffordshire but everyone there knows it and says it! Tbf, out of the 11 in my flat, not one had heard of 'gaybod'.
And for something that's funny and people describe it as 'jokes' or 'he is jokes' for a funny person.
Basically everything the stereotypical 18-21 year old says, look up chino wanker on twitter for a load of annoying phrases!
