Pain or Horny
When you're so confused about whether you're feeling like a broken robot or a walking erection that you just start yelling at the ceiling.
I was in the shower and yelled 'IS THIS PAIN OR IS THIS HORNY?' My roommate thought I was having a mental breakdown.
My mom called me and I said 'I'm not sure if I'm in pain or I'm just really horny.' She said 'you're just being dramatic again.'
I was eating cereal and said 'pain or horny? pick one!' My cat looked at me like I was crazy.
