Double Dip 

When someone takes food out of a bag or dips finger in a sauce, they lick their finger and put it back in for more..

hence the double dip

Emily: Can I have a crisp?
Amy: Yeah sure!
Emily: Thanks! *Takes crisp, licks salt off finger*
Emily: Can I have another one?
Amy: Go for it!
Emily: *Puts finger with all spit on it back into the packet*
Amy: Ew! You just double dipped me!

Eating a "French Dip" and executing a "Tea Bag" (SEE TEA BAG) simultaneously.

After engaging in a "69er" for a little while, I wanted each of us to soak up the memory, so we "Double-Dipped."
