A tardbanger is any person that does anything stupid. This also includes having sex with anyone who is stupid or does a lot of stupid things. A person that says something incorrect or makes an argument and ends up being wrong. A name to call anyone who makes the smallest mistake.
"Fucking tardbanger," muttered Katie after Ryan hit his thumb with the hammer for the third time that day.
