OK, heres what u do:
1. Get a can of some kind of soup(not red, lloks like blood, parents freak) like chiken noodle works good.
2 put it in a blender, and add some of the food u ate that night.
3 add some water for a more realistic look. whatever else u feel makes it look more like puke too
4. Hide it under bed
5. take it out at about 6:00 am b4 school, go to bathroom closest to parents room and make puking noises and pour half in toilet as evidence.
hide other half to use again so mom still thinks ur sick half way through the day.
6. Think how fucking clever u are
