Rump only likes rumplickers who lick his rump. Which is many on this forum.
And now, the Rumplicker song:

rumplicker, rumplicker,
Make me a lick,
Find me a find,
catch me a catch
rumplicker, rumplicker
Look through your book,
And make me a perfect lick
rumplicker, rumplicker,
I'll bring the veil,
You bring the groom,
Slender and pale.
Bring me a ring for I'm longing to be,
The envy of all I see.
