What is a rainbow kiss tiktok?

There's no single, universally known TikTok trend called "rainbow kiss." The term is likely descriptive and refers to several different types of TikTok content featuring kisses and rainbow imagery. These could include:

• Kisses with rainbow-colored makeup: TikTokers might showcase kissing scenes where one or both participants are wearing vibrant rainbow makeup, creating a visually striking effect.
• Rainbow-themed lip gloss or lipstick kisses: Videos could focus on the application and display of rainbow-colored lip products, often with close-ups of kisses.
• LGBTQ+ themed kisses with rainbow imagery: Given the rainbow's association with LGBTQ+ pride, videos might feature same-sex couples kissing with rainbows in the background or incorporated into the visuals.
• A specific TikTok sound or trend using the phrase: It's possible a specific audio clip or challenge on TikTok has organically become associated with the phrase "rainbow kiss," though this would need further information to identify.

To find relevant videos, searching TikTok directly using the term "rainbow kiss" or variations like "rainbow makeup kiss" or "gay couple rainbow kiss" (if that's the specific theme you're interested in) will likely yield the type of content you're looking for. Keep in mind that TikTok's algorithm and trends change rapidly, so what's popular today might not be tomorrow.
