baaarstard
A baaarstard is a person who acts like they're helping you, but they're really just making your life worse. They're like a pizza with no cheese.
My friend is a baaarstard. He said he'd help me clean my room, then threw my socks at me.
My dad is a baaarstard. He said he'd take me to the movies, then made me walk to the theater.
My brother is a baaarstard. He said he'd share his candy, then ate it all before I got there.
