To really fuck something up in a way only a rock star can do.
Me "Dude! What happened last night? Shit went sideways..."
Rock star "I stacy moored it and pissed my girl off on her birthday!"
When a girl with acid reflux deepthroats your cock thus causing a burnt tip
"This girl gave me.the best head the other day! She had no gag reflex, but she had acod reflux so it was a tip burner."
