The art of being exceptionally twat-like. Usually this role is filled by someone who is unaware of their obnoxious, clingy, and overall bitchy attitude and personality. Such girls are commonly running late to work/school, browsing forever 21, wearing leggings in the dead of winter, and dancing on tables to Lady Gaga.
Jenna's twaty attitude was getting on my nerves!
