Excrellent!
Or, roughly translated: 'Ah shit, that's wonderful'

I also came up with aeroplank the pieces of timber they use to construct flying machines, and (apologies in advance if this offends anyone) spermbonk but I failed to come up with a definition.
Same old problem, then!

Katie,
Spoonerism is where letters are 'swopped', like 'tot of rum' becomes 'rot of tum'.
My nephew when small said he liked 'splussel bouts'. There are some lovely examples on the Internet but my fondest memory of 'mixing up words' was an old lady who insisted on calling her bottled mixture 'SyrupaForniaCaliperFigs'.

All have a lovely rest over Christmas.

Regards,

Len

Don't know if it's strictly speaking a spoonerism but my favourite word mix is hypodeemic nerdle.
