Liverpool, UK - When TikTok user Madi wrapped her mother's Christmas present in a very particular way, she knew exactly what she was doing.

The 20-year-old from Liverpool, England, made the gift look like a large dildo and when it came time to hand it out, she turned on the camera.

But it was Madi's grandma that ended up being the star of the hilarious video. While her mom doesn't really seem to know what she's looking at, the elderly woman sits frozen in her chair with a look of sheer horror on her face.

The shocked reaction drew in more than 23 viewers, as well as 4.7 million likes and 35,000 replies, many commenting on the fact that Madi's grandma clearly recognizes that shape better than anyone in the room.

Many users wanted to know what was actually under all that awkward wrapping paper.

In another TikTok video, Madi explained that it was actually just an innocent perfume bottle.
