Related to mongoloid, a bongloid is someone who is annoying mostly due to the fact that he does things that only a baby or toddler would do (baby + mongoloid = bongloid). Bongloids often do things like pull their pants all the way down, exposing their ass crack, when taking a piss in a public urinal.
That kid is 7 years old and he still shits his pants sometimes. What a bongloid!
