IWBB is an acronym similar to BRB, but more verbose and less common. People typically send "IWBB" when messaging online or texting and need to leave a conversation but will soon return.
Most often, a BRB absence is measured in minutes or, sometimes, hours. For example, you might use it when pausing a convo to run a quick errand or drop the kids off at the pool, aka, go to the bathroom.
If you need to be gone for a longer period, it's best to use a firm goodbye. Some examples include, l8r, LUB, and gb.
