english in practice, đố vui 2...

[chiefsmoke]

since today is monday in order to cheer you up a little bit for the whole week ahead, let's try this small abbreviation challenge right here:

1/ A.K.A (ex, aka Chiefsmoke)

2/ O.B.O (ex, obo Chiefsmoke)

what do they stand for???

again there will be a "clap clap...well done" for the first one to answer.

note: Senior buddies not allowed, let's the Juniors try. (correction: let the Juniors try => correct version)
Chiefsmoke
