Quick junk food dip

Okay so someone brought this dip to our New years party earlier this year and it is so yummy!
I made it twice recently. The deal is that you have to dip Cool Ranch Doritos in this dip, nothing else tastes as good. Okay here is the yummy recipe:

1 16oz container sour cream
1 brick of cream cheese softened
1 peeled and grated cucumber
1/2 large onion grated

Mix all ingredients together and let sit in fridge for about 2 hours before serving.
This stuff is so awesome, make sure you buy two bag of chips otherwise you will run out!
