We all know that no one knows how to get under our skin quite like our siblings. From the nasty verbal jabs to literal physical jabs, our siblings have gone all out in torturing, humiliating and traumatizing us. Of course, we love them forever, but the marks of their tricks have no doubt left physical and emotional scars.

We asked our audience on Instagram what the most messed up thing they’ve ever done to a sibling was and boy were the responses wild.

“When I was about 12 my sister was 9, she had a bad habit of pulling my hair so one day when she was sleeping I decided to cut her hair.” veronicaortiz360

Dang if my sibling ever does this one to me

“When I was 12 and my brother was 13, I was SO mad that I thought about putting Nair in his hair soap, but I decided that that was too bad so instead I put clear hand soap on his toothbrush 😂” –thefaz3962

Better than the alternative…

Giving them their first scars

“Had a little ride-on car when we were little, which was my favorite. My brother liked to use it too much and ride around in it. So I offered to push him around in it (I was 5 and he was 1) but it ended up getting stuck on a crack on the sidewalk and it flipped over. He ended up getting a gash under his chin 😂 has the scar today.”- maria__clarisa

Everyone with this adoption joke…

“So many things… hit them with the vacuum cord, Made one think she was adopted and she believed it for years, you know older sibling stuff.” lillyesc

The ultimate blackmail

“When my brother was 17 and I 12, I found condoms and a thong in his room I blackmailed him for weeks until he snapped and told on himself 😂😂😂 I’m pretty sure I got in trouble for going through his stuff #dublestandard.” duhkarina

Using the Valentina on them

“My brother sleeps with his mouth open so I put some dog kibble in his mouth and then poured Valentina in with it brothers fell asleep so me and my Tia @nessasterk painted his toes, put make-up on him and sprayed perfume on his butt.”- morelia_real

Literally putting them on blast.

“Put my sister @j0celyn09 in the dryer, turned it on for a few seconds and got a royal spanking but she liked it, lol.”- hi.dspnz26

And finally using the ultimate scary weapon against them.

“My brother @edlose_chaidez was bothering and teasing me so I told him to stop if not I would throw a fork at him. He didn’t stop and while he was running away I threw the fork I had at him and hit his arm. He still has a scar from it. Lol.”- yara_nely
