YIB 

Short for Young Israel Booster - a particular sort of yuppie, often from Eastern USA or Tel Aviv who spends time on the Internet correcting people's wrongful impressions of Israel.

The Yibs flooded the YouTube video's comments pages with assertions that only Israel puts so much effort into reducing civilian casualties through precision strikes and anyone who says otherwise just doesn't understand what it's like to live in constantly threatened Israel.

"Yours in Brotherhood"

A way for fraternity brothers to close correspondence with another brother, most often in email.

Possibly an imitation of Scouting's common use of "YiS" for "Yours in Scouting".

Dear John,

We're moving the chapter meeting to 4p this Friday.

YiB,

Sam
