Masturbate whilst riding on a London tube train.
I was so desparate for a wank I had a crafty Warwick Avenue on the circle line the other day.
Sticking a mans balls up a womans vagina.
"yer man i totally took my spunk bells up her warwick avenue"
scott: geuss what i did this morning
chappers: what?
scott: i had a warwick avenue :)
chappers: oh me too!!
Warwick avenue is British slang for a sexual climax.
"I'm nearly at Warwick Avenue, don't stop"
"I'll take you to Warwick Avenue and back"
When one wishes to relieve them self of sexual anxiety by giving themselves a hand-job.
"Cor that bird was really fit I had to go home and give myself a warwick avenue..."
