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.

A picture taken of your shirt while it's on. Much like a selfie but only having the shirt visible.
Hey, did you see the shirt I bought? No? I'll take a shirtie and send it to you.

While wiping one's posterior region in a rush, there is a chance that the shitty paper will come in contact with the lower portion of one's shirt.
