Megalash 

A night of drinking, and drinking alone.

Going on the lash is okay for Friday nights or Saturday nights. But the megalash is for a night to end all nights. Where you pound down full bottles of vodka, where your pres start with shots and beer bongs, and you end up in a gutter by the end of the night.

Me: We going out tonight?
Mate: Ye, on the fucking megalash, mate. Let's get fucking rekt.
