Upspeak?

Not sure if that's a question mark or an exclamation mark above Martin's head?
I hate that upspeak malarkey? Usually teenage girls? Like when someone tells you something but they kinda don't sound too sure if you understand? Even though it's nothing more complicated than what Shaz said about Jules' hair?
I kinda hope you had a good flight Alan? Y'know that thing you do in the sky? OMG like you understood me in the first place? L8rs. etc.
