Aliases
All three members of De La Soul have used a number of aliases. The following are the most significant:- Posdnuos – Pronounced "pas-da-noos". The name may be a combination of the reversed words sop, meaning "leftover," and sound, a name Mercer went by while acting as a high school DJ. According to some sources, the fact that the words spelled backward are "sounds op " is intentional.
- Plug One – An early concept for 3 Feet High and Rising involved music being transmitted from Mars by three microphone plugs. Though this idea was abandoned, the titles "Plug One", "Plug Two" and "Plug Three" still became relevant on the album. Mercer's title of Plug One would eventually evolve into Plug Wonder Why, which has been shortened to Plug Won.
- Mercenary – Derived from the last name, "Mercer". This name was given to him by DCQ, brother of Mos Def.
- P-Pain – Caricature of the rapper T-Pain. He uses this alias in the song "Supervillainz" by DOOM.
