Physique of Speech: Something at First Something Else

We've all heard about "love at first sight" and I believe it exists. However, it's merely one of a multitude of emotions we subconsciously experience when we interact with someone for the first time. Here are some others that aren't as well known.

Good

Like at first look

Want at first witness

Romance at first regard

Arousal at first perusal

Smitten at first survey

Not so good 

Disappointment at first discovery

Indifference at first inspection

Confusion at first examination

Annoyance at first notice

Violent at first view

Bad

Split at first spot

Repulsion at first recognition

Vomiting at first monitoring

Suicidal at first scrutiny
Restraining order at first spy

Interesting

Puerile at first peep

Hunger at first ogle

Ovulation at first observation (for the ladies)

Erection at first detection (for the men, I hope)

Bedazzled at first behold (two meanings, substantial difference)
