From Sisqo's own mouth... “What I was really referring to was ― a dump truck when it backs up, it’s like, ‘beep, beep beep.’ So, ‘she had dumps like a dump truck’ is, like, when girls do a booty dance move and they look back at their butt. She’s like a dump truck back-back-backing it up.”

This was stated in an interview with HuffPost back in 2016.
Man, see that girl over there? She's got dumps like a truck!
