Build around common chat reactions
Start with reactions like wait what, no way, okay, sorry, thanks, I am crying, side eye, good job, and please. These ideas map directly to everyday messages, so people have a reason to send the sticker again.
Make the emotion readable first
A sticker can be clever, but it still needs to scan instantly. Big facial expressions, simple gestures, and short captions usually work better than complex scenes with tiny details.
Use meme formats carefully
Meme stickers are strongest when the format is flexible. Try expressions such as dramatic crying, fake shock, confused thinking, proud celebration, awkward silence, and low-energy disappointment.
