GAP's new Christmas 'viral' is objectionable for many reasons, most of which explain themselves when you click on this link. (Be warned, it will take you several hours to recover your equanimity.)
One admittedly minor quibble is the lack of a forward slash between two of the 'chant' names: Good luck with that bird (a chant about cooking your Christmas dinner) and You office party hardied (a chant about embarrassing yourself at the office party).
Run the two phrases together, as this site unfortunately does, and you have a very rude sounding chant.
Give us a P. Give us an R. Give us an O. Give us an O. Give us an F. Give us an R. Give us an E. Give us an A. Give us a D. Give us an I. Give us an N. Give us a G.
