someone who is pathetic or dull Lameass is a compound formed of two existing slang words: “lame” (which traditionally refers to a disabled or crippled person, and is often used to describe something weak, pathetic, or unimportant) and “ass” (which traditionally refers to “the part of the human body that you sit on,” and is often used to describe someone who is dull, vain, or absurd). The combination also serves as a slang term and essentially encompasses all of these negative adjectives that could be used to describe someone who is pathetic or dull.
