I get a little flakier
PS - Bacon souffle must mean something else or you wouldn't have asked about it. But I have no idea what. Maybe it's British. They'll say anything.
One man's pork brains are another's bangers and mash. Tolerance. It's a virtue.
Baked beans for breakfast is a relatively modern phenomenon - and anyway what's wrong wit bangers and mash - one of the beauties of english is the fun you can have with it!
PS Bacon souffle appears to be a quote from an Eminem lyric - and if it's slang it's not English English slang - nor does Google come up with anything suggesting it is slang.
First post ever on a forum answering a question so I'm a little excited to tell the truth
Anyway, "prongs" can sometimes be used to refer to legs, so the expression "look at those long prongs could be a reference to someone's lovely long legs.
Hope that helps
