A phone call by a friend to another friend at a predetermined time. Mostly used in bad situations,
first dates, or when someone goes somewhere they simply don't want to be.
Most times, a lifeline is used to show that
one friend is in distress, when he's actually chillin at
home with two beers, one in hand, and one waiting for the other friend. The distress
call is what gives the friend his opporunity to leave, and also gives the impression to whoever is litening to the phone
call that it's serious.
The lifeline remains the most efficient,
yet most underused method of ditching bad dates. Sometimes
hard to coordinate, lifelines prove their worth in effectiveness when your friend's girlfriend doesn't get pissed (and consequently, stop putting out) at your friend when you ditched her best friend on a date.
"Dude,
Steve, I got a date with
Jessica tonight at 7, give me a lifeline around 7:
45, and then I'll meet you at your pad."
