You may have heard of it as Lacrosse, it's what people who want others to know what the shit they're talking about call it.
Of course it's likely you still haven't heard of it because I only know what it is because Lacrosse players from east coast universities are apparently all rapists and murderers. Think that's how anyone not on the east coast learned it existed.
I though he was talking about an airport for a bit. Then I though he was calling people who dress a certain way lax, which is a weird descriptor to use for a person but maybe that's an east coast thing too.
