testipop 

Testipopping is when a adolescent boy's voice jumps or cracks while talking. This is usually seen as an embarrassing thing, as everyone will probably start laughing at you.

Teacher ~ "Class, can anyone tell me what the Chemical formula for water is?"

Boy ~ "<pop>YYeeesss</pop> Miss"
The "yes" part in this sentence is when the boy testipops in his enthusiasm to answer this nerdy question

Everyone laughs as the boy flushes in embarrassment.
