Well there's many ways just to say hi, u can say it in different tones or give facial and body expressions that change the kind of hi..... but here's some I like to say.

Hey there sugerpants!!
(On guys or girls, it's funny, specially on guys and shy girls)

What's crackalackin/what's crackin'

Quiondas vato! [Keee-On-das, vatoh]
(Spanish slang for what's goiing on dude)

Buttsex!
(When u hug a girl, hello or handshake a buddy to say hi, quickly make a RANDOM pointless and key:FUNNY comment, like buttsex and walk off, or laugh or w.e its up to you.)

Damn i m sure I can think of more but their not coming to me, lol the possibilities are nearly endless, watch comedies n pay attention to some funny movies, memorize funny or silly remarks or jokes and use them...Hope this helps

Just say Hi, but over your shoulder with body language facing away. If they are walking, walk infront slightly. Open oer shoulder but keep walking and dont give her any value, e.g face her until she is open.
