Gave My Sister A Wedgie How Do I Give Her A Wedgie?

How do i give her a wedgie? - gave my sister a wedgie

My sister told me the whole time when we were young, wedgie, and now I'm trying to retaliate because they put all their jeans in their underwear, and now it's slipping all the time. Whenever I see him that wedgie clutches my arm with her nails. Can anyone tell me a way to him without wedgie? (Like the damage that I will be left in the lurch)
