Combination of spazzing out and being jazzed up. Happens when one is extremely excited and nervous at the same time.
I had a busy day ahead of me so I had two 5-Hour energy drinks. When I got on the train, I saw a super hot girl and then started jizzing out like crazy!
And dying in yo' bed many years from now, would ya be willing ta trade all da days from dis here day ta dat fo' one chance, just one chance, ta come back here as young men an' tell our enemies dat dey may take our lives but dey will never take our freedom ... YUB NUB!
