Then my dad got a job
A putdown for a pupil who has some brand new article of clothing or possession and has brought it into class to show off. Engage them in conversation and tell them that you really like the coat/bag/whatever and in fact you used to have one yourself a while back, before finishing with "but then my dad got a job". At this point, you may commence the pointing and laughing.
