Wham, Bam

Overheard snippet of conversation, from plump West Indian woman in her mid 30s with short, bleached hair to another woman in her late 40s,

"...but 'wham bam' for you may be different than 'wham bam' for another woman, you know, 30 minutes might be 'wham bam.' For me, it's good when it puts me to sleep...and there have been a lot of sleepless nights."
