Oh, kinda forgot to answer the topic in my last post.
A great and subtle way that definitely would work on me would be to spend a lot of time with me and be the one to take initiative of the hangout. After hanging out for a full day, ask if he wants to hang out the next day too, it shows you're not sick and tired of hanging out with him after a whole day and sends him a signal that you like him. A girl that with me once, I took her to a pizza place and she liked it and suggested we should come back and try out every pizza on the menu. That's about 30 dates or so, at least I knew she didn't hate me.
This would have me laughing and blushing like crazy. x_xGo up to the person and ask for their hand. Draw a line across it and explain that its a really big river, and the bunny on this side (doesn't matter) really needs to get to the other side. Ask how he does it. Give cute little answers as to why the bunny can't cross the river (i.e., ...bunny jump in river, bunny goes *glubglubglub*.) When the person finally asks how the bunny is supposed to get across, give them the cute puppy eyes and say "I don't know, I just wanted to hold your hand."
I jokingly flirt all the time but I know it's a big joke and I'm usually the 'tom boy' or 'best friend' to any guy so he knows I'm joking too and I can be pretty smooth, perverted, and hilarious about it. If I guy starts letting on that he's actually flirting with me I get super nervous and I fail and resort to stupid things you'd say back in middle school and I turn super innocent.
A line I used the other day, "Excuse me, I know this sounds extremely dense but are you actually flirting with me?"
haah i didn't notice that typo either xD
my friend once said to a girl:
Him: "Hey, Do you know who your boyfriend is?"
Her: "no.. "
Him: "It's me!"
and it worked.
