My ex's little brother was 130 lbs at age 10. His family ordered pizza once a week and got cinna-stix with it once. I was standing in the kitchen and watched this little ham take the almost full cup of icing and dip his finger in and lick it off. Looking at me, smiling....no shame. I deliberately gave him the most disgusted look I could and he butthurtedly said "Whaaat?" I outright told him it was gross and he whined like a dog and kept eating. He wasn't even licking it off entirely, so the saliva icing mix on his hand was going right back in the cup........so fucking gross.
