to pretend to sympathize and care about what another person is saying. Often the word "Praysheout" is said immediately after in order to bring closure to any further unwanted discussion about something very boring and stupid.
Person 1: "I was so sick last week...my head was..blah..blah..blah..etc...
Person 2: "ohsahboutdat"
(If "PRAYSHEOUT" is not stated immediately after, than "ohsahboutdat" must be repeated often.)
Usually coupled with "ooorill", this saying really lets the other person know that you could not give a shit less.
"Man...my girlfriend is really giving me shit about going to the Danger Danger Concert"
