dont beat about the bush just come right out with it and hope that they like u back hehe
Flash him your ****.
Say, "I like you."
Simple. Be direct and honest. Just be open to him/her about your feelings. That way you get a definite answer. It wont leave room for guesses and misinterpretation.
english to bodyonics transl. -(grab his/her heine and smile coolly)
the english version is probably less risky (and definantly less risque!)
Straight up and ask them if they like you because you like them.
