Mike Wass of Idolator called it a slow jam and contrasted its "soft and mellow" sound with DeLuna's past music, which was frequently uptempo club music.

As part of a press release, she described the sample as "evidence that music transcends generations" and said "Bam Bam" had "left [a] musical imprint culturally". "The Fader"'s Rawiya Kameir cited "Bum Bum" as a possible indicator of dancehall's resurgence in mainstream media. Throughout the song, DeLuna gives instructions to a lover, such as: "We can do it in the shower / We can do it on the floor / You can get it every hour, there's so much more." She teases her partner: "Go hard but don’t break it". Trey Songz's verses include "Shawty came in and she caught me red handed staring at her butt"; Kameir said he acts like a "charming lothario".
