When a couple goes out to a romantic dinner, stuffs their faces, and boil up hot steamy ones. Then, they both undress and the man sits on the toilet and the woman sits on his thighs, facing him. At this point, the couple locks lips and their "love bombs" slide out of their rectums almost perfectly together, forming a heart in the toilet bowl.
Mary and Donny have a great relationship together. They go out to eat, feel the passion of the flame, and drop sensual love bombs to show their affection. That's love.
