What does the word on the Barcelona uniform mean?

the pattern is the Catalan version of the club's team song "El Cant del Barca":

Totel Camp

Esunclam

Som la gent blaugrana,

Tantseval d \' on venim,

Si del Sudo del Nord,

ARA ESTEM D\’ACORD, ESTEM D\’ACORD,

UNA BANDERA ENS AGERMANA.

BLAU GRANA AL VENT,

UN CRIT VALENT,

TENIM UN NOM,

EL SAP TOTHOM:

BARCA ! , BARCA! , BARCA! ,

JUGADORS,

SEGUIDORS

TOTS UNITS FEM FORCA

SON MOLTS ANYS PLENS D\’AFANYS,

SON MOLTS GOLS QUE HEM CRITDAT,

I S\’HA DEMOSTRAT, S\ ’HA DEMOSTRAT,

QUE MAI NINGU NO ENS PODRA TORCER.

BLAU GRANA AL VENT,

UN CRIT VALENT,

TENIM UN NOM,

EL SAP TOTHOM

BARCA ! BARCA! BARCA!

English:

We shouted at the stadium

We are Barcelona fans

We came from all directions

regardless of age and color

The flag was flying high

Blue and purple were its color

The team was fighting bravely

Let's shout its name

Barcelona Barcelona!

The players and fans are United

We are invincible

We have scored many goals

No one is your opponent

The mighty Barcelona is invincible

The flag is flying high

Blue and purple are its colors

The team is fighting bravely

Let's call its name-Barcelona Barcelona.
