1. Making someone very angry so they turn black instead of red/ to skip work but longer because its deep blue ("Blau machen"= making blue in german)
2. To attack someone by flailing around your legs with your hands
3. Having to do all the work yourself/ A card trick but without using any cards

I dont know if this counts as cheating since my mothertongue is german and dutch and german are quite similiar but i thought i might give it a try :D
