If you're looking for a way to express feeling weird in a nonsensical way, you could try:
* Using random words and sounds: "Blorf, snarglesniff, flibbertigibbet!"
* Mimicking sounds of discomfort: "Ugh, yuck, blech!"
* Making strange facial expressions: Raising your eyebrows, wrinkling your nose, sticking out your tongue.
However, these methods would only communicate a sense of discomfort or strangeness, not the specific concept of "making someone feel weird."
Remember, the point of gibberish is to be nonsensical, not to convey specific meanings.
