Person A: Last night I hooked up with a chick and I swear, as she neared orgasm, her moans started to sound like "Mary Had a Little Lamb"
Person B: Wow. What a sexaphone!
The noise made by the ball sack slapping against one's taint while making a thrusting or side to side hip motion. This can only be done while wearing loose fitting underwear or no clothes at all.
While Jim was dancing to Crank Dat in his boxers and knee socks, the noise made by his sacamaphone was deafening.
Puting your penis in a telephone while talking to your girlfriend. When he says "hello" you jizz right in the mouth piece and say you gave me head hoe and then hanging up and never talking to her again.
TreyQuan: Picks up phone
