Portuguese Diesel Blowout

Is the act when a female is riding a male cowgirl. And when he’s about orgasm she jumps up and kicks the mans nuts. A similar act to a Portuguese gas pedal.

My man was being an ass all day so decided to have fun with him and at the end I gave him a Portuguese diesel blowout

fart dieseling

Da embarrassing (or hilarious, depending on who you talk to, and/or whether da emotions-feeler is da "actor" or da "observer") interval of "run-on" dat sometimes occurs following da "main event" --- i.e., yer butt-trumpet keeps on "purrin' like a kitten" for an extended period afterwards, rather than just "saying its piece" and then being done wif it.

In da uproarious "National Baked Bean Month" speech, da formally-dignified speaker experiences a major bout of fart dieseling towards da end, totally goofing up said oration but majorly putting his audience in stitches.
