The last person, out of a group
of friends, to have had sex with a new sexual
partner. It is seen as a badge
of honour, this because
the "flag bearer" is often seen as the representitive of the groups sexual
appeal and conquest as a whole.
Man 1: "Yo, man 2, flag bearer
Man 3: "As if he is! lol"
Man 2: "... does a blowjob
Man 1: "No... but kudos on reaching 3rd base, though at this rate you'll never
be flag bearer
Man 3: "I bloody hope not! As if I'd let this loser be flag bearer
for long! lol"
