Shirty

[Jessica]

Flustered and [pompus], like you would be if someone asked you a question you find incredibly offensive. Happens a lot with teachers and snobby upperclassmen.
Another British bit of fun. Used in Angus, Thongs, and [Full Frontal Snogging] and [Harry Potter and the Goblet of Fire]. See snogging.

[Gregory]

Bad-tempered or annoyed.

[Julian]

Irritable; querulous.
