Sister slap

When someone wants to slap someone but they’re too close to you so you don’t.

I want to sister slap my best friend but she’s my bestie so I can’t.

A sister slap is a slap that may be administered by an older sister to a younger sister, when said younger sister is acting a fool

Yo, my younger sister got a speeding ticket so I gave her a sister slap...across her face
