Clogged sink EMRGENCY PLEASE HELP!!!!!?

I poured some liquified chocolate down the sink and now it's clogged. The sink has a procesor (whirling blades that cutup food). I tried turning them on but all it's doing is spitting back up chocolaty water. The pipe is also at ninety degrees. I need to fix this before my mom comes home and eats me alive, can anyone help me please?!
