This seemingly innocent term (which derives from the art of 'bumping' iphones) is used to refer to people of the opposite sex who are attractive and 'Bump Worthy'.

Now used on nights out as a discreet indication to friends of potential men whom are worthy of a look and possibly even a smile. It tends to replace the word 'fit' which in our eyes is too obvious, tacky and lacks any element of subtley.

In addition - Power Bump refers to the elite members of the bump force, who are so attactive that they take our breath away. Generally these are celebrities and basically; exceedingly good looking - in every way. Almost everyone agrees on power bumps.
