When you have a thought, then something totally ridiculous happens, and you COMPLETELY loose that thought. You were just monkey fucked.
You are sitting at a bar talking about some stupid bullshit, and then a car out side EXPLODES:

Person 2: Holy shit! ...What were you saying?
Person 1:... I have no idea.
Person 2: You been monkey fucked, fool.
