who doesn't :)
Young girls might say 'i feel all Gooey' or 'he gave me goosebumps' or 'I had butterflies'. Of course they would never say this to their crush :)
Gooey is a strange word to use, because Goo is like slime or Mucus, but not in this context. it is definitely an internal feeling, like nausea but pleasant. Definitely only used in this context by young girls, and is mostly out of fashion now.
'Goosebumps' is sometimes an emotional response, but it can be a response to cold, or to fear. It is a description of your skin when your hairs stand up, it causes the skin to look like the flesh of a plucked goose or chicken.
'Butterflies' is also an internal, fluttery feeling (flutter is the action made by a butterfly, or the sound&action of a bird making a short flight). It can be an emotional response, but also a response to dizziness (i get butterflies when I go too high on the swing, at the park)
It is more common in english to describe the object of your affection, and add action to show the emotion that it inspires. "He's so handsome... (Sigh, dreamy gaze, big smile). Note that these sorts of spoken expressions are usually open ended, not requesting any response, stated in a way that it is clear the speaker is saying their thoughts aloud, partly for their own pleasure, partly to share their pleasure.
