A slap across the face with so much force that even Hellen Keller hears it.
Me: Shit! Hellen I think someone just got a French Bitch Slap, did you hear that?
Hellen Keller: MMMMMGAKLHJJIHORFKHFA!!!!!
Me:... Umm I have to go now.
Just like the awkward salmon, only done with three fingers and done very sloooooooowly.
Sneak up behind someone and yell "Awkward Sloth Slap" Gently place three fingers between the persons legs and move them side to side ever so slightly brushing their inner thighs.
