Wee

If you ride a thrilling rollercoaster, you might organically release a "Wee!" scream of excitement without even thinking. People may use it in all sorts of contexts, whether shouting, texting, or typing it as a comment on social media.

For example, your friend may share that she is cancer-free in a text, and you reply with "Wee! Wonderful news!!!" Or, your cousin may share a picture of her newborn baby on Facebook, and you comment, "Congrats! It's so great to have another girl in the family! Wee!!"
