wall boast

to flaunt your achievements on someone's facebook wall, with a message masquerading as a lighthearted, spontaneous 'hello' to your buddy but purely for the benefit of your mutual friends.

becca: emma, i've had enough of your wall boasting. i know that you met a hot guy on saturday because i was there. and he wasn't that hot. and your ex clearly never reads my wall anyway.

emma: worth a shot though?

becca: pathetic.
