whiffle swear 

Pulling off on a swear word such as "shit" so that the consonants are exaggerated. So "shit" would be pronounced as "shhhhhhhhhhhhit" with a hard "t" at the end. Often used when goofing around, and not want to sound harsh when swearing.

After losing a game of ping pong I exclaimed, a whiffle swear

Am Swear 

A Slang way of saying "I swear" and "I swear to you" at the same time.

Saying "Am Swear" holds a lot more weight than "I swear" because it's not only that you swear, but also that you swear to the person at the same time.

"Bro, Am Swear Bro, I kissed her."
