That depends on how you discover the deed... Were you invited?
try talking with this girl, and see what happens
if an another girl likes your sexy and cute boyfriend then go up to that girl and tell her that your boyfriend is all ready taken by you. then see what happens after that talk. quietly spy or peek around that girl and see if she's doing anything sad, mean, awkward, or interesting!!
girl die so ugly
Talk to her more, become her friend and see what happens from there
She does not want you to see what (or who) she is doing there.
The best way is to ask her out and see what happens
click on it, and see what happens
if you want to make a girl nasty just lift her skirt and see what happens or try touching her body
you can find it by the act she is doing when she meet or see you lol
2 ways: one, if ur the same gender kiss them and see what happens, tow, hire a guy and a girl to kiss her and tell you what happens!! 2 ways: one, if ur the same gender kiss them and see what happens, tow, hire a guy and a girl to kiss her and tell you what happens!!
Wait and see what happens.
either 1) he realizes the girl sees him doing this 2) he realizes he looks creepy doing this or 3) both 1 and 2.
