Your best friend my possibly think your attractive or like you.
Get her consent first.
grab your own
First grab a friend then talk about him after that talk to and pretend he's your best friend
It's important to ask for and respect consent before touching someone in any way, including grabbing their butt. Make sure the person feels comfortable and is willing before making any physical advances. Remember that consent is key in any type of physical interaction.
NO they dont..
If she doesn't know you well and like you a lot, then "angry" is probably the best description.
I say both. First grab the breast then squeeze it
grab his butt
Yes
not a good idea If you're sure she'd feel comfortable with it grab away. If you're not sure and you're in public you might want to avoid that. Best idea is to whisper in her ear "I wanna grab your butt" and gauge her response. :)
That she is ticklish.
You grab your best friend and saltine, put the saltine on yourself somewhere without your friend seeing and he then has to find it
