The name of this potion is clever.
"unction" Eng. an ointment, derived from a Latin term meaning "to anoint with oil"
"oblivious" Eng. forgetful, derived from a Latin word
"Ubbly" suggests "bubbly", but also suggests the suffix "-uble" which is derived from Latin and means "able to", so that the name of this potion might then be read as "able to forget".
