Friend: "How'd it go with you and Michelle last night?"
You: "Went great, I've been saving a water balloon all month for her."

A Czech waterballoon is when someone puts MDMA or MDA in the tip of a condom that has had a hole poked in the tip & then place's the condom on an errect penis before initiating sex, the fluids from intercourse then mix with the mdma and slowly squirt out with the bonus being when the man ejaculates it mixes and then absorbs and squirts out into the partner getting both parties high.
