Originating from the English West Country, including the city of Bristol.
Originally meaning "great" as in "great big" or "gurt big", but now is also used in place of "really", "well", "very" and "exceptionally".
These can also be abreviated to simply "gurt"
"That bendy-bus is gurt lush!"
(Not necessarily but usually done and said in a manner involving a situation when: Semen is released in large quantities, released internally, while relieving immense stress (sexual tension), in a single load. So basically to discharge sperm very aggressively inside of your partner's vaginal region or any other orifice that can be penetrated and or injected with semen "a big cream pie".)
2) A slang for Semen, brought about by the fact that semen seems to some what resemble plain yogurt (Gurt if shortened) when spilled on certain surfaces, and or when leaking from a woman vagina or any person's skin after sexual intercourse.
2) (random dude) "Sorry I didn't mean to shoot gurt all over your sheets."
