welsh crumble 

The welsh crumble symbolises the proverbial spineless welsh man combining the words "crumble" and the dirty term "welsh".

Used in context -

"That Jonathan Russell, he's a welsh crumble" - meaning he is spineless or weak; or
"crouch, set, bind, engage, welsh crumble" - referring to the welsh scrum; or
"i'm going to turn her vagina into a welsh crumble" - referring to a dirty welsh pudding.

Notably, very similar to the term "wetty", "wet lettuce" or "pussyhole" alike, and can be used in similar ways.
