Yes, the canonical use of the verb slashdot means that as a result of a website being listed in a Slashdot entry, its server is overwhelmed by requests as folks click on through. Believe me, I noticed when I got listed in /. because my DSL bandwidth evaporated within minutes. For a week or so, I was getting up to a couple of hits per second. I still get a lot of traffic from the /. and the Snopes pages.
