The time of year (typically after the March equinox & through the September equinox) in which the act of avoiding someone with half'assed excuses/flat out DISMISSING someone's advances - becomes rampant. Essentially, a "quick exit" when faced with being pursued by an unfavorable suitor. Often used as pick-up line - grenade - or ugmo repellent.
Lame excuses for the following, but not limited to...
• not wanting ANYTHING to do with you physically or romantically(present or future, while denying the past if any).
• having already gotten services rendered from you (be it free drinks/weed, a ride, money, oral sex, sex ect) and wanting you in their lives on more sporadic terms until more services are commissioned at a more convenient/(much) later date.
• clichés used when not wanting to get/be tied down in a serious/monogamous relationship.
• pacifying phrases given to a person in hopes that they're dumb enough to stick around while you're at play.
