"Blend of Tra and Shawn"
The name Trashawn is commonly a male name from the "American" origin.
Trashawn is a modern American formation that follows the pattern of names such as DeShawn, LaShawn and RaShawn, in which a short syllable is placed in front of Shawn. Shawn is an English spelling of the Irish name Sean, which derives from John. The name first appears in United States birth records in 1982, which is consistent with this kind of twentieth-century American coinage rather than an older inherited name.
The pronunciation of Trashawn is truh-SHAWN.
