Warchalking 

The practice of marking a series of symbols on sidewalks and walls to indicate nearby wireless access.
Typically with the SSID written above the symbol and Bandwidth below.
Inspired by the practice of hobos during the Great Depression to use chalk marks to indicate which homes were friendly.

I warchalked the secret government agency down the street!

war chalking 

The practice of leaving coded chalk marks on or near buildings or sites where a "war driver" has identified available 802.11 wireless network access. The marks usually indicate the type of access and level of security.

This practice is decended from the way hobos used to chalk mark the curbs outside homes where an easy mark could be approached for food or other handouts.

I located a particularly handy open wifi network near the ballpark, so I warchalked it for my hacker brothers and sisters.

An Irish phrase meaning shit, derived from ass

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."

Breadhead

A breadhead is like a crackhead, but for money instead of crack.
