Not Mark Buehrle.
Mark Buehrle is not an ace.

to reserve your seat when you get up. must be called while your butt is still in the seat. also, someone else has to be a hearing witness of what you said, so that when you come back and some dueche bag is sitting in your seat, you can be like, "well joe heard me call aces, right joe," and joe wil be like, "ya dude i heard ya, sorry bud"
"Aces on this seat dudes, brb"

A Canadian street gang, easily noticeable by their leather jackets. Members will claim to be vigilantes who are fighting against the government to take back the power, which was never lost in the first place. Members also enjoy gaining attention by any means necessary, and are mugged frequently, on average about 5 times per day. Should be noted, members do possess "steken" like qualities.
"Hey Aces, Communism doesn't work!"
