WBTYM 

Wham Bam Thank You Ma'am
Wham, Bam, Thank You Ma'am currently refers to a quicky (sex with little to no foreplay).

The oldest reference to WBTYM is Dean Martin's 1950 song Wham! Bam! Thank You Ma'am! In this song Dean Martin is making reference to a woman breaking his heart which can be seen in the following lyrics:

(Wham bam thank you ma'am) Hope you're satisfied
You took my heart and tore it apart you hurt me deep inside
I'll never be a fool again you really crushed my pride
(Wham bam thank you ma'am) Hope you're satisfied
