Oh! Good to know thanks guys. The baby bump was my first thought too, but that comment just never seemed to fit the post! Haha
'Bump' is commented simply to make.the post stay high up on the list of conversations so it dont fall way at the bottom and not get an answer
Or some people put it so that someone will answer there question lol it bumps your question up so people will see it
People write "bump" to "bump" up the post to the top of the forum if they want more discussion and their post has trailed way down the page.
Lol! It means baby bump, (your stomach) as it gets bigger
