A quick, no-fuss greeting meaning hello, alright, or what’s up. You fling it at anyone, mates, strangers, the postie, no big ceremony. Tone’s everything, it can be warm and friendly, a bit surprised, or even lightly nosy like you’ve clocked something’s gone off. Often written as ay up or ey up too.
"Ayup, you’re reyt? Tha’s made a right mess of it. Come in, stick t’kettle on then, and tell us what’s been happenin’."
