A denial hint is when u are asked by someone of something that they heard of that is either embarrasing or straight up stupid and u playfully or sarcastically deny it to indirectly tell them without blurting it out in public.
1.When Demarcus asked me about the horrible incident between me and Jazmine at the party, i gave him a denial hint.
2. Kevin-Hey Courtney, i heard that you finally let Dre get some at that party last week
Courtney-*Smiling* ummm...no....what are you talking about Kevin???
Kevin-Ohhh ok....cool *Turns over to Greg* She was sooo giving me a denial hint
