MUD Mug
The abbreviation of Muck Up Day; a tradition that occurs in many schools (mostly private) on the last day of lessons for year 12s. Pranks are pulled on the rest of the school, including kidnappings, stink bombs, cod liver oil on banisters, viagra in the water supply and releasing three sheep labelled 1, 2 & 4 onto the school grounds (the groundsmen look for sheep #3 which doesn't exist). Students also personalise their uniform (rip it up...). Water guns/bombs are also used and occaisonally students will hiijack the PA system. School shirts will often be signed with 'MUD (insert year)'.

nice.
Sent this to my crush now she has a restraining order on me!!!
Without this mug, my life was but a series of painful unfortunate events. Since it has come into my life, love has followed, joy has followed and dishonour has been disavowed. Sincerely. From the bottom of my heart. Thank you. Please keep up the good work and I hope everyone will find joy as I have one day.
I love the Duh Big Red Truck so much that I have a tattoo. So does my best friend. We’re in our 60s. Woot woot!
