Suppressing routes in BGP

Can someone give me a very freeze dried explanation of this.  Obviously it is used with the "aggregate-address".  By "suppressing" what does this mean.  Explain it to me like I'm in sales or something :)

<By "suppressing" what does this mean.>

Basically "suppressing" is "not advertising". [determining what routes not to advertise]

Two methods are available in BGP to implement route aggregation.
You can redistribute an aggregated route into BGP or you can use a form of conditional aggregation.

Basic route redistribution involves creating an aggregate route and then redistributing the routes into BGP.

*Conditional aggregation involves creating an aggregate route and then advertising or suppressing the advertising of certain routes on the basis of route maps, autonomous system set path (AS-SET) information, or summary information.
