three-fingered booger
a legal case that a lawyer cannot bring to an end or otherwise get rid of despite great effort and expense. Such a case usually loses the attorney money, harms his/her reputation, and has little social value.

"Man, what a booger finger..."
"No!"
"Man, what a booger finger..."
