Krisi;
"use plain English" is a whole different can of words.
Do you mean United Kingdom English, Irish English,American English,Australian English, or Canadian English ?
New worlds and meaning enter language every year, Anyone who watches Ru Paul or attends CD/TG events will pick up such terms.
Some like the OP might use the terms in their everyday social group.
Years ago , I lived in southern California and started surfing, I had to pick up Valley Speak just to meet people my own age.
Consider the following, which could be heard in just about any pub in England , arguably the most English speaking country in the world:
"Bloody hell mate! A fortnight ago I was down the local having a chin-wag with this fit bird, feeling pretty chuffed with myself, when some dodgy-looking bloke came up and started getting lairy with me. I don't know what he was on about; I thought he was taking the piss, but he wouldn't stop giving me aggro. I reckon he must have been off his tits. Next thing I knew the Old Bill had shown up and nicked this geezer before he could scarper. What a load of ********!"
