look up any word, like dirty sanchez:
 
1.
It is the epic type of slushy

The crazy insane suicidal flavor of slushy

Its when you go to a place with more than one flavor of slushy and you combined them all together to create a super mixture.
Person 1 - "Hey I am going to the gas station. Want anythin?"

Person 2 - "Ya get me a suicide slushy."
